Warning!

Puhti and Mahti will be decommissioned after Roihu becomes available. Users should clean up unnecessary files and move any required data by the end of August 2026. See the Roihu data preparation instructions for details.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

Star-CCM+

Simcenter STAR-CCM+ is a commercial Computational Fluid Dynamics (CFD) based simulation software developed by Siemens Digital Industries Software. Simcenter STAR-CCM+ allows the modeling and analysis of a range of engineering problems involving fluid flow, heat transfer, stress, particulate flow, electromagnetics and related phenomena. Formerly known as STAR-CCM+, the software was first developed by CD-adapco and was acquired by Siemens Digital Industries Software as part of the purchase of CD-adapco in 2016. It is now a part of the Simcenter Portfolio of software tools (Wikipedia).

License

CSC - IT Center for Science has no own Star-CCM+ licenses available for customer use on CSC's computing platforms. Instead, user may purchase for her or his own use a Power-On-Demand (PoD) license to be used on the servers, for more information, see this web page.

Available

Several versions of Star-CCM+ are available on Puhti, Mahti and LUMI servers. Use command

module spider starccm+

on the server to check the installed versions. The double precision version will have the -R8 suffix on the end of the module version number.

On LUMI, you need to first load the module environment, and then give module spider command

module use /appl/local/csc/modulefiles
module spider starccm+

Usage

There is a batch job script example available on the Puhti and Mahti servers in:

/appl/soft/eng/starccm+/parjob_starccm+

On LUMI, the example batch job file is available here:

/pfs/lustrep3/appl/local/csc/soft/eng/starccm+/parjob_starccm_lumi

Copy the file and modify it for your own use. Further instructions are given in the file and the documentations of the platforms.
