How to use StarCCM

Software	Version	Cluster
StarCCM	17-04-007	Dardel

The Star-CCM files can be accessed by loading the appropriate modules. To see which versions of Star-CCM+ are available use the command

module avail starccm+

In order to use StarCCM+ at PDC you must provide your own license for the software. You can either use the environment variable

CDLMD_LICENSE_FILE

to set to point to the correct license server (not the PoD server 1999@flex.cd-adapco.com), or get access to STAR-CCM+ through license keys generated “power-on-demand” with additional options in the command line

-podkey your_license_key -licpath 1999@flex.cd-adapco.com

where “your_license_key” is the license key.

Running on the Batch system
