Minimum Hardware Requirements

Learn the minimum requirements for supported platforms.

Supported Platforms

SimSolid supports Windows and Linux. The Linux version of SimSolid works without any user-interface and is meant to run jobs on HPC clusters.

Note: As of October 14, 2025, Microsoft Windows 10 will reach its end of support. Following Microsoft's messaging, all Altair 2026 applications will no longer support Windows 10. Altair is providing this information to help our customers prepare and accommodate for this change. Altair 2026 will support the Windows 11 operating system, along with our other Linux-based operating systems. Please contact your local Altair support teams if you have any questions or concerns.

Windows

Operating System

Windows 11 (64-bit) on Intel i7 based computer or higher

Memory

At least 4 cores and 16 GB of RAM

Graphics Hardware

OpenGL graphics card, version 3.1 or higher
Only dedicated AMD, Intel® Arc™, and NVIDIA graphics cards are supported (integrated onboard Intel chipsets are not supported)

Hardware Settings

The following options are available:

Change the number of cores/processors used by the analysis solver. By default, the application detects and uses all available cores/processors during the computation to maximize the performance. The number of cores used can be decreased, if desired, to reserve some cores for other computer processes.
Check the Use scratch files checkbox to use scratch files when running an analysis. Scratch files are written to a user-defined location, with the default location being the Temp directory. This functionality is useful for large assemblies with several million degrees-of-freedom as this helps reduce memory usage.
Clear all entries in the Windows registry related to the application, such as material database location, and so on.

Linux

Operating System

Red Hat Enterprise Linux 8.4 (64-bit)
Oracle Linux 8.4 (64-bit)
SUSE Linux Enterprise Server 15 SP3 (64-bit)
Rocky Linux 8.4 (64-bit)

Memory

At least 4 cores and 16 GB of RAM
