Application Details

  • Description: Produced by Siemens CD-adapco (Computational Dynamics-Analysis & Design Application Company Ltd), star-ccm+ is used for computer-aided engineering, in particular, computational fluid dynamics (CFD).
  • Versions : 15.02.009 ( + R8) and starccm+/18.04.009.R8
  • Module names : starccm+/15.02.009 (and starccm+/15.02.009.R8) and starccm+/18.04.009.R8
  • License: University of Hull Engineering department, restricted by POD license.

Important information

  • Important: where possible it is recommended to use versions 18.04.009 and 15.02.009, versions 14 will be retired soon.
  • The SIM data processed should be the same version of the star-ccm+ application, there is a strong sensitivity in this program.
  • Multiple node processing will need the addition of the file in $HOME/.ssh/config (with StrictHostKeyChecking no)

Star-ccm server

Star-ccm+ can be used as a server within an interactive session on Viper. This would be very useful for graphics from big simulations.

  • Check SSH keys are been generated correctly for this version of SSH.

Known Issues

  • After version 14; no noted MPI issues.
  • After version 18, internal Intel MPI is used.
