System Requirements

Minimum requirements: 5 GB of free disk space, 8 GB of RAM
Recommended: 50 GB of free disk space*, SSD (solid state disk), 16 GB of RAM**

*Large amounts of free disk space and fast disk reading / writing is especially required for Process Metallurgy Module calculations. Using caching in TC-Python / TC-Toolbox also requires large amounts of free disk space. 

**If running multiple calculations in parallel (for instance multiple calculations in graphical mode, multiple console windows, or parallel TC-Python / TC-Toolbox calculations), 2–6 GB is required per calculation — depending on the used database and number of elements

Discontinued Platforms

Below are the previous and upcoming platforms that we have dropped support for.

  • Support for installing and running the Thermo-Calc software package on Windows 7 and Windows 8 has been dropped as of the Thermo-Calc 2021b release. Users with Windows 7 or Windows 8 are therefore advised to migrate to a newer operating system.
  • Support for installing and running the Thermo-Calc software package on all 32-bit platforms has been dropped as of Thermo-Calc 2018a. Users with a 32-bit platform installation are therefore advised to migrate to a 64-bit platform.
  • Support for installing and running the Thermo-Calc software package on Windows XP has been dropped as of the Thermo-Calc 4.1 version release.
Roadmap for Platform Support

System Requirements for SDKs

Windows 64-bit

Software 64-bit
TC-Python* Requires a Python installation with Python 3.5 or higher (we recommend Python 3.10) and a Python distribution (we recommend Anaconda).
TQ-Interface** Requires a Fortran compiler. We test the API with Visual Studio 2010 and ifort 16.0.4.
TC-Toolbox for MATLAB®** Requires a compatible version of MATLAB® installed, with a working license. We support MATLAB 2019b up to MATLAB 2022b.

*TC-Python has a few package dependencies. They should install automatically. However, this might not work behind a company-proxy server. See the TC-Python documentation for solutions.

**Other compilers may work, but we do not provide support for them.

​Linux 64-bit

Software 64-bit
TC-Python* Requires a Python installation with Python 3.5 or higher (we recommend Python 3.10) and a Python distribution (we recommend Anaconda or the Python interpreter of the system).
TQ-Interface** *** Requires a Fortran compiler. We support two:

  • If you compile your code with ifort 16.0.4, link with libtq-linux-x86_64-ifort-*.so. The resulting binary might require a recent GCC be installed to run on another Linux computer.
  • If you compile your code with gfortran 4.4, link with libtq-linux-x86_64-gfortran-*so. The resulting binary might require a recent GCC and libgfortran.so.3 be installed to run on another computer. Note that libgfortran.so.3 is installed as a part of gfortran 4.4.
TC-Toolbox for MATLAB® Not available

*TC-Python has a few package dependencies. They should install automatically. However, this might not work behind a company-proxy server. See the TC-Python documentation for solutions.

**Other compilers may work, but we do not provide support for them.

***On Ubuntu version 20.04, only ifort 16.0.4 is currently supported. 

Mac 64-bit (macOS)

Software 64-bit
TC-Python* Requires a Python installation with Python 3.5 or higher (we recommend Python 3.10) and a Python distribution (we recommend Anaconda or the Python interpreter of the system).
TQ-Interface Not available
TC-Toolbox for MATLAB® Not available

*TC-Python has a few package dependencies. They should install automatically. However, this might not work behind a company-proxy server. See the TC-Python documentation for solutions.
