www.FactSage.com

(revised May, 2022)

FactSage 8.2 is a major update with extensive modifications. For example, the databases FactPS, FToxid, FTsalt, FTmisc, FThall, FTlite, FScopp, FSlead, FSstel, and SpMCBN have been updated in FactSage 8.2. In addition two new databases have been added - FTsulf and SGTE(2022).

There is also a new app - OptiSage - Calphad Optimizer.

The FactSage 8.2 Update/Installation enables you to install FactSage 8.2 into a new folder or on to a new computer.

The changes in FactSage 8.2 are compatible with FactSage 8.0 and FactSage 8.1 but they are not backward compatible with earlier versions (7.3 and prior). You can install FactSage 8.2 as either a new installation or simply update an existing FactSage 8.0 or FactSage 8.1 installation.

The total number of files is now over 17,000.

What follows is a list of the more important programming, database and documentation changes in FactSage 8.2 (2022) with respect to FactSage 8.1 (2021).

  • FactSage Start-up


  • FactSage 8.2 Update/Installation/Menu
    • Download FactSage 8.2 - The FactSage 8.2 Update/Installation program contains the complete 8.2 package of software, databases and documentation. It can be downloaded from the Internet in two different ways.
      1. Download FactSage 8.2 via FactSage 8.1

      In the FactSage 8.1 Main Menu Window click
      Tools > FactSage Updates >Download the complete FactSage 8.2 Update/Installation Package .

      If you are entitled to FactSage 8.2 the file CD-FactSage81.exe (approx. size 350 MB) will be downloaded to the downloads folder. Typically this takes 10 - 20 minutes or even longer.

      2. Download via www.factsage.com

      For details visit www.factsage.com and click 'Download Service' and then 'FactSage 8.2 Update/Installation'.

      For certain installations it may not be possible to download the file - for example you may get an error message such as 'webpage cannot be found'. This could be because the security settings on your computer are blocking the transfer of a ".exe" file or the file is too large to be downloaded. Check with your IT group.

    • FactSage Installation - The FactSage 8.2 Update/Installation program is a one-stage installation and update program. The program runs a self extractor that automatically performs the extraction operation before starting the installation. We recommend that you do not upgrade any FactSage 7.0 - 7.3 currently installed on your computer. Rather you should install FactSage 8.2 into a new folder or upgrade any FactSage 8.1 currently installed on your computer See below (Update/Refresh FactSage 8.2) for more details.

    • Show Me - For details on FactSage 8.2 Update/Installation refer to the Show Me documentation. FactSage 8.2 may be installed as

      • Standalone Single User- the complete FactSage package will be installed on the computer. The program cannot be accessed by other computers. The Standalone computer requires a security key (dongle) attached to a USB port.
      • Network Server- the complete FactSage package will be installed on the computer in a public folder that is 'share read-only' to other computers on the network. The files can be read and copied by other computers (Network Clients). In a small network of several computers the FactSage Network Server can be any computer, but not a virtual machine.
      • Network Client - only the FactSage modules and databases will be installed on the computer. The computer will have access to the documentation, example, figure, etc. files already installed in FactSage on the Network Server.

    • Server/Client Installation - For a client installation on the network, the program FactSageClient enables the Client workstation to locate the Server installation. The program is run prior to the FactSage 8.2 setup program and is well-suited for Windows 7, Windows 8, Windows 10 and Windows 11 installations. Details are given in ShowMe which is part of the installation package.

    • Server/Client Update - If the FactSage Client is already running FactSage on a network installation and the Server installation is then updated (for example a new version or new databases), the Client installation will not be updated until a new day. This default action can be overridden - to immediately update FactSage on the Client workstation, in the FactSage Main Menu of the client PC click on 'Tools > FactSage Network > Refresh Client installation ...'.

    • Windows Vista, Windows 7, Windows 8, Windows 10, Windows 11 - FactSage 8.2 has been successfully installed and tested under Windows Vista, Windows 7, 8 and 10 operating systems. All programs run as designed including the Solution module (see below). The dongle drivers distributed with FactSage 6.4 (or earlier) are outdated. The latest drivers (see below) are very well suited for installing under Windows 7, Windows 8, Windows 10 and Windows 11.

    • Windows XP no longer supported by Microsoft - FactSage should still run under Windows XP even though Windows XP is no longer supported by Microsoft. According to Microsoft if you continue to use Windows XP now that support has ended, your computer will still work but it might become more vulnerable to security risks and viruses.

    • Sentinel HASP Drivers - FactSage MemoHASP dongles are more recently referred to as the Sentinel LDK security keys. The dongles are supplied by THALES. FactSage 8.2 employs installation software from SafeNet Inc. and it is fairly straight forward to install the drivers. For instructions click on 'Tools > Sentinel Security Key > Information ...'

    • FactSage dongle status - When a valid FactSage dongle is attached to a USB port on the computer you are able to run a standalone version of FactSage. If FactSage issues an error message about a 'missing or invalid FactSage security key' it goes into the FactSage SetUp mode with a green screen. There are several factors that can cause this to happen.

      The FactSage dongle status displays the status of the FactSage dongle attached to the computer. This helps you to diagnose the source of the error message.

      • Run FactSage 8.2 and display the FactSage Main Menu.

      • Click 'Tools > FactSage dongle status > Explanation of dongle status... ' and follow the instructions.

      The 'FactSage dongle status' Window shown here is for an installation where a valid FactSage dongle is attached and everything is in order (i.e. 1 - 5. All OK).



  • Update/Refresh FactSage 8.2

    The FactSage 8.2 Installation program enables you to update/refresh FactSage 8.2 software, documentation and databases to the full FactSage 8.2 package.

    You can upgrade FactSage 8.0 - 8.1 to FactSage 8.2. However we recommend that you do not upgrade any FactSage 7.0 - 7.3 currently installed on your computer.

    You can update/refresh a FactSage Standalone computer or a Network Server. In the case of a network installation it is only necessary to update/refresh the Network Server.

        This is the recommended setting.

      • Do NOT automatically update Profiles82.ini
        - in order to update Profiles82.ini you must first select Check for updates ... and then select 1. Update Profiles82.ini.
        This setting is not recommended.


      For the updating to succeed the following conditions must be satisfied:

        - your computer has access to www.factsage.com
        - you are running FactSage 8.2 as a standalone or server installation i.e. not network client installation


    • FactSage 8.2 Updates - automatic update of Profiles82.ini

      When you first run FactSage 8.2 the program tries to connect to www.factsage.com and check if your installation has the latest Profiles82.ini.

      If you have checked Automatically update Profiles82.ini the latest profiles file is downloaded and installed. In such a case you are notified that the following operations will be performed:

    • - the expiration dates will be refreshed

    • - any new dongle will be activated

    • - new databases will be installed/updated.
    • All of these actions will be done automatically.

      Important - after updating the profiles file it is no longer necessary for you to quit FactSage and refresh the installation.


    • FactSage 8.2 Updates - automatic notification - this is as before

      When you first run FactSage 8.2 the program tries to connect to www.factsage.com and check if your installation has the latest special databases and patches.

      If you have checked Automatically update Profiles82.ini the latest profiles file is downloaded and installed as shown above.

      However, if you have NOT checked
      Automatically update Profiles82.ini
      when necessary an 'Updates are ready.' message is posted in the FactSage Main Menu.

  • FactSage 8.2 Setup Files
      This was first introduced in FactSage 8.0. Each time FactSage is run a check is performed to make sure the important installation files (principally *.exe and *.dll) have not been inadvertently deleted.

      For example, Windows Defender (Microsoft Security) may suddenly decide a particular file (for example FS-Copy.exe) is a virus threat and delete it without notifying you. The rules of virus detection are constantly evolving. Even if a particular file has not been updated a file considered safe yesterday may be classified as a threat today.

      When an important file is missing you will now be made aware of the problem.

      Note:
      The *.exe and *.dll files are regularly vetted for viruses via www.virustotal.com that has access to over 70 antivirus software. Whenever the antivirus software reports suspicious behavior in one of our files we try and contact the antivirus vendor and report the file as a false-positive.


  • FactSage Slide Shows and FactSage Applications - 'Information > Slide Shows ...' and 'Information > FactSage Applications ...'

      A new slide show for Optisage - the Calphad Optimizer - has been added.

      The slide shows

        FactSage Overview - a quick look at FactSage Modules and Databases
        FactSage Browser - a navigation tool for database documentation
        Compound - for the Compound App
      have been updated.


  • FactSage Add-ons Menu

    This is new in FactSage 8.2. You can run Apps, Add-ons and shortcuts through the new FactSage Add-ons Menu.

    New Apps, Add-ons and their associated files can be stored in the sub-folder \Add-ons_Apps. The menu command lines for the Add-ons etc. are stored in this sub-folder in the text file Add-ons_Apps.dat that you can edit.

    This new option is directed to both regular and advanced users. It is versatile and simple to program.

    The following is a partial listing from the file showing the 4 command lines associated with the screenshot below.

    
    ;Microstructure.exe                 ;EQUIThermCond.pptx ;Microstructure App              ; The Microstructure App is used calculate the thermal conductivities of microstructures. Model parameters for thermal conductivity calculations are available in several FactSage databases. _  _   The thermal conductivity of phases can be calculated as a function of temperature, porosity (intragrain porosity) and size (average grain size).;
    ;EquiSage.exe /F90IOe /TDB /EQUILIB ;ConvTDBintro.htm   ;ConvTDB App to import TDB files ; ConvTDB converts a TDB file to produce both compound (.cdb files) and solution (.sln .fdb files) databases. _  _  In FactSage such databases are stored in separate files.; 
    ;EquiSage.exe /EQUILIB /FTOPT       ;FactOptimal.ppt    ;FactOptimal shortcut            ; This shortcut runs Equilib and loads FactOptimal ; 
    ;EquiSage.exe /EQUILIB /MACRO  Macros\EquiEx_SET_Variables.mac; ;Run Equilib macro       ; Run macro Macros\EquiEx_SET_Variables.mac 
    

    There is no limit to the number of add-ons, apps and shortcuts that can be included in the Add-ons Menu.

    For more details click 'Add-ons > Add-ons, apps and shortcuts ...'


  • Miscellaneous

           - c:\Program Files (x86); Windows Defender and CPU; Renaming the FactSage folder; HTTP vs HTTPS; Windows 11

    • Installing FactSage in c:\FactSage vs c:\Program Files (x86)

      We encourage users to install FactSage in the root directory, for example c:\FactSage, c:\FactSage82, etc.

      In FactSage there are over 17,000 files. With Windows Explorer it is easy to access the FactSage main folder (c:\FactSage etc.) and its subfolders that contain data (\FACTDATA), documents (\FACTHELP), figures (\FIGURES), macros (\MACROS\, etc. Private user folders (\PRIVATE, \USER ..) can be readily created and user files (*.equi, *.phas ..) easily moved between the subfolders.

      However IT may prefer you to install FactSage in c:\Program Files (x86) with the other 32-bit applications (do not store in c:\Program Files which is reserved for 64-bit applications).

      Installing in c:\Program Files (x86) is acceptable but it is not as easy to manipulate the files in c:\Program Files (x86) \FactSage. Care must be taken not to affect other applications. Note, all the data and user files will also be stored in c:\Program Files (x86) \FactSage and not in c:\ProgramData.

    • Windows Defender and CPU - adding an exclusion to Windows Security

      The Antimalware Service Executable (MsMpEng.exe) is a background-running anti-virus service in Windows Defender. It may have a detrimental effect on CPU and cause unnecessary delays when running FactSage. The effect on CPU is displayed by the Task Manager (to bring up the Task Manager press Ctrl+Shift+Esc).

      With all the FactSage programs and data stored in the one location it is fairly easy to add the root directory (c:\FactSage, c:\FactSage82, etc.) to the Windows Defender's Exclusion List and stop Windows Defender from unnecessary file checking.

      For example, go to Start > Settings > Update & Security > Windows Security > Virus & threat protection. Under Virus & threat protection settings, select Manage settings, and then under Exclusions, select Add or remove exclusions. Select + Add an exclusion > Folder > ... For more details Google 'Add an exclusion to Windows Security'.

    • Renaming c:\FactSage81 as c:\FactSage82

      Renaming the FactSage directory is straight forward. Let us say FactSage is installed in c:\FactSage81 but you wish to change the name to c:\FactSage82

      1. Use the Windows Explorer and rename c:\FactSage81 as c:\FactSage82

      2. Locate the text file Factwin.ini - i.e. c:\FactSage82\Factwin.ini.
      You can delete Factwin.ini in which case a new Factwin.ini will be generated with default settings.

      Or you can edit the text file Factwin.ini and globally change all text strings 'c:\FactSage81' to 'c:\FactSage82'
      This will assure that the list of connected databases, the list previous files and other personal settings are retained.
      But be careful when editing, do not corrupt the file!

      3. When you run FactSage (c:\FactSage82\FactSage.exe) the new/edited Factwin.ini will be refreshed.

      4. You may wish to edit the FactSage short-cut on the screen and change its name and properties. Point to the FactSage icon on the screen, mouse-right-click and select Rename and Properties.

    • HTTP: vs HTTPS:

      Most of our URL links have been converted to the more secure HTTPS protocol - for example https://www.FactSage.com - FactSage home page; https://www.crct.polymtl.ca - CRCT home page; https://gtt-technologies.de - GTT-Technologies home page.

      In addition to encrypting the data transmitted between the server and your browser, the HTTPS protocol protects the transmitted data from being tampered.

    • Windows 11

      To date we have seen no major issues when running FactSage 8.2 under Windows 11.


    2. Apps:


  • Information

    • FactSage - getting started ... - called from 'Information > FactSage - getting started ...'.

    • Add, change or delete your name

      This enables any user at this installation to modify (add, change, delete) his name and email address.

    • The image is intentionally blurred.

    • FactSage-TEACH - called from 'Information > FactSage-Teach ...'.

      FactSage-TEACH is a selftuition package on FactSage developed by GTT-Technologies. It is combination of a special handbook, a series of special mini-databases for use with the assignments, and a special flowsheet model for the Silicon Arc Furnace process. It is the result of a long series of seminars, training courses and workshops on Computational Thermochemistry which began in the early nineties using ChemSage. For more information including the 'Table of Contents' click 'General > FactSage-TEACH > Introduction ...'.

  • FactOptimal    

    • What's new in FactOptimal in FactSage 8.2

      Some minor bugs have been fixed.

      The app is also accessible as an Add-on
      - in the FactSage Menu Window click Add-ons > FactOptimal ....


  • Phase Diagram


  • OptiSage - Calphad Optimizer
      The OptiSage App is used for the assessment of Gibbs energy data. Various types of experimental data (phase diagram, enthalpy, activity data etc.) can be utilized in order to generate optimized parameters for the Gibbs energies of stoichiometric compounds as well as the excess coefficients of a wide range of non-ideal solution models.

      In FactSage 8.2 there are now two OptiSage Apps - the traditional module that was developed in the early 2000's, and a new module that has been completely re-written. To reflect this major change the new app is named Calphad Optimizer.

      The aim of a Calphad optimization is the determination of thermodynamic parameters that allow reproduction of all available experimental data. The Calphad Optimizer is combining a clear and easy to understand user interface with strong optimizers and extensive user feedback.

      Most popular experimental data types are pre-defined and there is a test option to detect typos as soon as they are made.

      Two different optimizers (Gaussian Process and NOMAD) are included and the user is presented with feedback during and after the optimization.

      Through the feedback, Calphad Optimizer gives you control over the optimization progress - you are able to see the current status of the optimization and what experiment and fitting parameters are most sensitive.

      Note: The Calphad Optimizer is not included with the standard FactSage installation because of the large size of the OptiSage package (1.3 GB). It is necessary to download the packge from the Internet.


  • Viscosity

      The viscosity algorithm has been completely restructured.

      The Viscosity App in FactSage 8.2 performs calculations approximately ten times faster than in earlier FactSage versions.


    3. Databases:


       In the FactSage Main Menu Window click Documentation for detailed information on the public compound and solution databases.


  • Thermochemical TDB databases - converting to FactSage databases

      In FactSage 7.3 GTT-Technologies developed a new utility, ConvTDB, whereby Thermochemical Database (TDB) format could be converted to FactSage databases (.cdb .sln .fdb) format. ConvTDB has proved to be very useful.

      Following the feedback from users ConvTDB has been updated for FactSage 8.2.

      In addition, a minor bug leading to underestimation of stability of pure magnetic elements has been fixed. All calculated equilibria have been corrected, only the activity information of pure elements might have been wrong.


  • FactPS - the FACT Pure Substances Compound Database

      Complete details on FToxid 8.2 including all the phase diagrams are given in the updated Documentation in the FactSage Main Menu Window.


  • FTsulf - the new FACT Sulfide Database

      The new FTsulf databases contain solutions and stoichiometric compounds in the Cu-Fe-Ni-Co-Cr-Mn-Pb-Zn-As-O-S system evaluated/optimized by the FACT group for applications involving equilibria among metal, liquid and solid sulfide phases, liquid and solid oxide phases and gas. This includes pyrometallurgy, hot corrosion, etc. The FTsulf solution database contains sulfide solutions and three major metal solutions (liquid, bcc and fcc), which are compatible with the sulfide solutions. The FTsulf compound database contains all stoichiometric sulfide, sulfate and arsenide compounds evaluated/optimized by the FACT group to be thermodynamically consistent with the FTsulf solution database.

      For nearly all calculations involving sulfide solutions, the FTsulf databases supersede the FTmisc databases. In particular for calculations involving matte smelting, the FTsulf databases will provide better results in nearly all cases due to many improvements to the optimizations [2135-2139, 4023-4028, 4031-4035]. For example, the MAT2 phase is now more consistent with the FToxid and FSstel databases, contains oxygen as a component, and can be used at all compositions from pure metal to pure sulfide.

      FTsulf 8.2 should NOT be used simultaneously with the FTlite, FScopp or FSlead databases.

      Complete details on FTsulf 8.2 including all the phase diagrams are given in the updated Documentation in the FactSage Main Menu Window.

      Solid salts (94 phases)

      Ag2O AlCl3 CaAlCl5 CaFeCl5 CeCl3 CeF3 CoAl2Cl8 FeSiO3_S1 CoF2 CoFe2Cl8 CrAl2Cl8 CrCl2 CrCl3 CrF2 Cs3CeCl6 CsCe2Cl7 Cu2O FeAl2Cl8 FeCl2 FeCl3 K2CeCl5 K2CoCl4 K2FeCl4 K2O K2PbCl4 K2ZnCl4_S1 K2ZnCl4_S2 K3Ce5Cl18 K3CeCl6 K3Mn2Cl7 K4MnCl6 K5Zn4Cl13 KAlCl4_S1 KAlCl4_S2 KCoCl3 KFeCl3 KFeCl4_S1 KFeCl4_S2 KMnCl3 KNiCl3 KPb2Cl5 KZn2Cl5 LaF3 Li2CoCl4 Li2FeCl4_S1 Li2FeCl4_S2 Li2MnCl4 Li2NiCl4 Li4CoCl6 Li6FeCl8 Li6NiCl8 LiAlCl4 LiCoCl3 LiFeCl4 LuF3_S1 LuF3_S2 MgAl2Cl8 MgFe2Cl8 MgO MnAl2Cl8 MnCl2 MnF2_S1 MnF2_S2 MnFe2Cl8 Na2CoCl4 Na2FeCl4 Na2Mn3Cl8 Na2MnCl4 Na2NiCl4 Na2ZnCl4 Na2O_S1 Na2O_S2 Na2O_S3 Na3Ce5Cl18 Na6MnCl8 Na9Mn11Cl31 NaAlCl4 NaFeCl4 NaFeO2_S1 NaFeO2_S2 NaFeO2_S3 NaMn4Cl9 NiAl2Cl8 NiCl2 NiFe2Cl8 Rb2CeCl5 Rb3CeCl6 RbCe2Cl7 TiAl2Cl8_S1 TiAl2Cl8_S2 TiCl2 TiO_S1 TiO_S2 ZnCl2

      Liquid salts (5 phases)

      MgCl2 PbCl2 MnCl2 CoCl2 NiCl2
      In addition the updates to the database include the following changes.

        The Li cation has been added to the SALTK liquid solution (which was originally Na, K // NO3, NO2, Cl, CO3, ClO4 in FactSage 8.1).

        Four new compounds LiClO4, LiNO2, KLi(NO3)2 and KLi3(NO2)4 have been added to the compound database and three compounds LiNO3, Li2CO3 and KLiCO3 have been updated.

        LiClO4 has been added to the PERC solid solution, and two new LiNO2-rich solid solutions (LiNA and LiNB) have been introduced.

        The SALTK liquid solution permits calculations for nitrate-rich solutions. The reciprocal ternary sub-systems Na, Li // NO3, NO2; K, Li // NO3, NO2; Na, Li // NO3, Cl; K, Li // NO3, Cl; Na, Li // NO3, CO3; K, Li // NO3, CO3; Na, Li // NO3, ClO4 and K, Li // NO3, ClO4 have been newly evaluated and optimized at all compositions (including all binary common-ion sub-systems), based on the experimental data available in the literature. This includes updates for the K2CO3-Li2CO3, KNO3-LiNO3, Li2CO3-LiCl, Li2CO3-LiNO3, Li2CO3-Na2CO3, LiCl-LiNO3 and LiNO3-NaNO3 binary sub-systems.

        In SALTK, LiX-NaX, LiX-KX and NaX-KX (where X = NO2, Cl, CO3 or ClO4) as well as LiCl-Li2CO3, NaCl-Na2CO3 and KCl-K2CO3 (which were already available in SALTF) are the only solute-solute binary common-ion sub-systems that have been optimized.

        Note that reactions of the type 4 ANO2 + BClO4 = 4 ANO3 + BCl (where A, B = Li, Na or K) have a very negative Gibbs energy change and thus are strongly shifted to the right. In order to inhibit those reactions (which may be kinetically hindered), it is possible to use virtual elements (This new feature was introduced in FactSage 8.1). Some detailed examples are provided in the Equilib Advanced Slide Show (see in particular example 15.6).

      The total number of stored FTsalt phase diagrams is now 367 (was 351 in 8.1).

      Complete details on FTsalt 8.2 including all the phase diagrams are given in Documentation in the FactSage Main Menu Window.


  • FTmisc - the FACT Miscellaneous Database

      The FTmisc databases contain data for sulfides, alloys, etc.

      In FTmisc 8.2 the MAT2 liquid sulfide/metal solution, and all solid solutions and stoichiometric compounds compatible with it, have been moved to the new FTsulf 8.2 database.

      For the matte smelting system (S-Cu-Fe-Ni-Co-Pb-Zn-As), the remaining sulfide solid solutions and stoichiometric compounds are compatible with liquid matte [FTmisc-MATT]. This system has been superseded by the new FTsulf 8.2 database, which provides equally good or better results for most applications.

      In FactSage 8.2 modelling of approximately 60 'end-members' associated with several different phases has been completed to allow calculations for 4- or higher-component systems. Such calculations should be viewed as interpolations of somewhat lower accuracy than that associated with the fully assessed lower-order systems. In addition, a small adjustment to the assessed data for the liquid phase of the Nb-C system now avoids calculation of an inverse miscibility gap at very high temperatures in the liquid phase.

      Complete details on SpMCBN 8.2 including all the phase diagrams are given in Documentation in the FactSage Main Menu.


  • TDMeph - the MEPHISTA-15 nuclear database developed by IRSN.

      A minor bug leading to underestimation of stability of pure magnetic elements has been fixed. All calculated equilibria have been corrected, only the activity information of pure elements might have been wrong.

  • TDNucl - the NUCLEA-15 database developed by IRSN.
