System Requirements

As a general requirement, 2 GB of disk space is required for installation and 8 GB of RAM is recommended for reasonable performance.

Furthermore, a minimum of 50 GB of free disk space and preferably use of an SSD (solid state disk) is recommended for running Thermo-Calc and its SDKs. Not all calculation types require this much free disk space, but some rely heavily on saving and reading files from the hard drive, particularly Process Metallurgy Module calculations.


CPU Requirements

To run Thermo-Calc 2020b, 2020a, 2019b, 2019a, 2018b, 2018a or 2017b, the CPU needs to support SSSE3 instructions. Read about this instruction set. Learn what architectures support what instructions.

Roadmap for Platform Support

Support for installing and running the Thermo-Calc software package on Windows 7 and Windows 8 will be dropped after the 2021a release, planned for December 2020. Users 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.
