What's New in FactSage 8.1


(revised April, 2021)

The FactSage 8.1 Update/Installation enables you to install FactSage 8.1 into a new folder or on to a new computer.

The changes in FactSage 8.1 are compatible with FactSage 8.0 but they are not backward compatible with earlier versions (7.3 and prior). You can install FactSage 8.1 as either a new installation or simply update an existing FactSage 8.0 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 8.1 (2021) with respect to FactSage 8.0 (2020).

2. Modules: 3. Databases: 4. Previous FactSage Updates

1. General:

  • FactSage 8.1 News
      After installation you should periodically check the latest news about FactSage 8.1 where we immediately report any 'bugs' and other issues as they surface.

      You can display this latest news - in the FactSage Main Menu click
      'Information > FactSage 8.1 ~ News ~ from www.FactSage.com ...'

      Alternatively visit www.FactSage.com > 'FactSage 8.1 ~ News ~'

      FactSage 8.1
      ~ News ~

      The 'bugs' and other issues highlighted in the previous 'FactSage 8.0 ~ News ~' have been resolved.

  • FactSage 8.1 Update/Installation/Menu
    • Download FactSage 8.1 - The FactSage 8.1 Update/Installation program contains the complete 8.1 package of software, databases and documentation. It can be downloaded from the Internet in two different ways.
      1. Download FactSage 8.1 via FactSage 8.0

      In the FactSage 8.0 Main Menu Window click
      Tools > FactSage Updates >Download the complete FactSage 8.1 Update/Installation Package .

      If you are entitled to FactSage 8.1 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 8.1 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 8.1 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 8.1 into a new folder or upgrade any FactSage 8.0 currently installed on your computer See below (Update/Refresh FactSage 8.1) for more details.

    • Show Me - For details on FactSage 8.1 Update/Installation refer to the Show Me documentation. FactSage 8.1 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 8.1 setup program and is well-suited for Windows 7, Windows 8 and Windows 10 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 - FactSage 8.1 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 and Windows 10.

    • 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 8.1 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 8.1 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 8.1

    FactSage 8.0

    FactSage 8.1

    The FactSage 8.1 Installation program enables you to update/refresh FactSage 8.1 software, documentation and databases to the full FactSage 8.1 package.

    You can upgrade FactSage 8.0 to FactSage 8.1. 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.

    Note the 'Refresh databases' option has been discontinued in FactSage 8.1 since it no longer serves a useful purpose.

  • FactSage 8.1 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, Microsoft Windows Defender 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.

      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 ...'

    • Slide Show on the Theoretical Background of FactSage

      (These changes were made for FactSage 8.0 but the file was omitted from the installation package.) The Slide Show on the Theoretical Background of FactSage has been revised and enhanced. An interactive Table of Contents has been added to the Slide Show. In conjunction with this the various chapters and their respective pages have been numbered. On the last page of each chapter a return button has been inserted to take the reader back to the Table of Contents page. A chapter has been added dealing with the theoretical background of EMF cell calculations. Such calculations can be executed using the Reaction module. The chapter on Phase Diagrams has been expanded.

    • Slide Shows on Equilib

      See Equilib re updates to Regular Features and Advanced Features and new slide shows
      Physical property calculations and Thermal conductivity of microstructures.

      If you have checked Automatically update Profiles81.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 8.1 Updates - automatic notification - this is as before

      When you first run FactSage 8.1 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 Profiles81.ini the latest profiles file is downloaded and installed as shown above.

      However, if you have NOT checked
      Automatically update Profiles81.ini
      when necessary an 'Updates are ready.' message is posted in the FactSage Main Menu.

  • Documentation - FactSage Browser
    • The total number of stored phase diagrams has been increased by approx. 200.

  • Virtual elements

  • ChemSage files

    • New file naming convention

      In FactSage 8.0 the file naming convention PROG*.dat was replaced by a more versatile *.prog where prog is the 4-letter APP description, for example *.ehph, *.pred, *.reac, *.equi, *.phas and *.mixt.

      In a given folder both PROG*.dat and *.prog file names are permitted but the * must be unique. For example, only one of say EQUIMyCalc.dat and MyCalc.equi is permitted. This new naming convention has been well received and requires no modification.

      In FactSage 8.1 the new naming convention has been extended to ChemSage files where the name *.dat is replaced by the more useful *.chem. Both *.dat and *.chem ChemSage ascii files are permitted. Note the *.cst ChemSage transparent files remain unchanged.

    • New [SHORT] and [LONG] summaries - 'Equiib > Reactants > ChemSage files > Summary of ChemSage files ...'

      The 'Summary of ChemSage files ...' now offers two options

    • [SHORT] - the traditional brief summary of ChemSage files

    • [LONG] - a new detailed summary of ChemSage files including the list of system components, the list of phases and the list of phase constituents of each mixture phase
    • All the *.dat, *.chem and *.cst ChemSage files are stored in the \ChemSage subdirectory (ex: c:\FactSage81\ChemSage).

  • View Data

    • What's New in View Data - 'View Data > Help > What's New in View Data ...'

      The link What's New in View Data has been updated and gives a summary of the more important programming changes in View Data that have appeared since FactSage 6.1 (2009) until now FactSage 8.1 (2021).

    • Vitual Species - Qa, Qb, Qc ... Qz

      In FactSage 8.1 it is possible to create private databases containing "virtual elements" Qa, Qb, Qc ... Qz.

      These private databases may be accessed by View Data in the usual manner.

      The screenshot is a partial listing of virtual compounds stored in the VIRT database.

  • Equilib

    • What's New in Equilib - 'Equilib > Reactants Window > Help > What's New in Equilib ...'

      The link What's New in Equilib has been updated and gives a summary of the more important programming changes in Equilib that have appeared since FactSage 6.1 (2009) until now FactSage 8.1 (2021).

    • Equilib STOP Window - 'Equilib > Parameters Window > Stop & Sound Window > yes'

      By pressing the 'STOP button' in the STOP Window you can terminate Equilib (and Phase Diagram) at any time. If the program gets hung up or refuses to quit, go to the FactSage Main Menu Window. At the top click 'Tools > Reset programs ...' and follow the instructions on how to 'kill' (terminate) the program.

      Typically the STOP Window is placed in the upper right corner of the screen. For some users this position may not be convenient.

      In FactSage 8.1

        - the STOP Window is now always kept on top - that is, it is no longer hidden by other Windows.
        To hide the STOP Window simply click its minimize button '-'.

        - it is possible to drag and drop the STOP Window to any position on the screen.
        This new position is then used the next time the STOP Window is displayed.

  • Macro Processing

    • Run Macro menu - 'Equilib > Reactants Window > Run Macro ...'

      'Run Macro' has been added to the Menu of the Equilib Reactants Window.

      This enables you to immediately rerun the last macro that was loaded.

      The 'Run Macro' menu button is equivalent to 'Equilib > Reactants Window > File > Macro Processing > Run macro ...'

    • What's New in Macro Processing - 'Equilib > Reactants Window > File > Macro Processing > What's New in Macro Processing ...'

          - show the macro window (also see MACRO_HIDE)
          - MACRO_SHOW TOP - place macro window at the top center
          - MACRO_SHOW BOTTOM RIGHT - place macro window at the bottom right corner. New in 8.1  
          - stop the calculation after TIME_CALC_SECS_LIMIT exceeded
          - this redefines the 'time limit' posted in the STOP Window
      $SOLGAS - compilator and date ex: "Lahey_2020-12-18" "Intel_2020-12-18"
          - used by FactSage developers, new in 8.1
        - $E_s?*$ - product species * = 1 - 5000; ? = a, D, d, E, f, g, h, l, N, n, R, s, W, w, X ...
        - these values are only defined after the equilibrium has been calculated (CALC) i.e. $E_OK$ = 'OK' 
      $E_so*$ = species "o" flag in Equilib Results; assumed to have zero molar volume (1=True, 0=False)
      $E_sT*$ = species "T" flag in Equilib Results; data are extrapolated above maximum T limit (1=True, 0=False) 
      $E_sV*$ = species "V" flag in Equilib Results; modeled with an equation of state (1=True, 0=False)
      Examples of "o" "T" "V" flags are given in the updated EquiEx_List_Results.mac
      located in the Macros Folder.      
      Elements:  - atomic numbers expanded to 132 (was 99)
        - updated $ELEMENT_NAME('atomic number') $ELEMENT_NUMBER('name')  
        - new $ELEMENT_NAME-FULL('atomic number') $ELEMENT_NUMBER_MAX 
        for up to 132 elements including "virtual elements".
      Example is given in the new EquiEx_List_Elements.mac located in the Macros Folder.

      and the total number of slides is now 141 (was 129).

  • Phase Diagram

    3. Databases:

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

  • Thermo-Calc TDB databases - converting to FactSage databases

      In FactSage 7.3 GTT-Technologies developed a new utility, ConvTDB, whereby Thermo-Calc 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 8.1.

  • FactPS - the FACT Pure Substances Compound Database

    • FactPS is the compound database for use with the FACT databases (FToxid, FTsalt, etc.).

    • The following species have been added to FactPS:
      KClO4(liq), Na2Ca3Al2F14(s), Na4Ca4Al7F33(s), NaClO4(liq)

  • FTdemo - the FACT Demonstration Database

    • FTdemo is the name for the old FACT Slide Show database developed around 2001. Although FTdemo is part of FACT Package of Databases, it is for demonstration calculations only. It should be used only for teaching - for example with the Slide Shows.

    • For calculations where the results are important, you must NOT use the FTdemo database. Use the FactPS compound database and the FToxid, FTsalt, etc. databases. For detailed information on the FactPS, FToxid, FTsalt, etc. databases go to the FactSage Main Menu and click on Documentation.

  • FThall - the FACT database for Hall aluminum process

      The FThall database contains the elements Al-Mg-Na-Li-Ca-F-O-C. It is used for thermodynamic and phase equilibrium calculations involving liquid metal - cryolitic bath - Al2O3-based oxides in alumina reduction electrolysis cells, and for molten aluminum treatment with fluoride fluxes.

    • In FactSage 8.1 the thermal conductivity and the volumetric properties data have been updated for 4 liquid salt phases:

        LiF, NaF, MgF2, CaF2

    • Note: in Equilib the thermal conductivity and the volumetric properties are only calculated if the "include molar volume data and physical property data" option in the Equilib Menu Window is checked.

  • FTlite - the FACT Al-alloy and Mg-alloy Database - formerly known as the FACT Light Metal Alloy Database

      FTlite is primarily designed for thermodynamic and phase equilibrium calculations involving Al alloys and Mg alloys. Calculations involving Ti alloys and Li-Na-K-Mg-Ca-Sr-Ba mixtures can also be performed but not to the extent as for Al- and Mg-alloys.

    • Most Co-RE systems (except Pm, Eu, Tb, Yb and Lu) have been integrated into the FTlite database. These are useful for calculations involving magnets and the recycling of magnets.
