Using STAR-CCM+ via OnDemand

STAR-CCM+ is a complete multi-disciplinary platform for the simulation of products and designs operating under real-world conditions. Using STAR-CCM+ on Apocrita via OnDemand allows you to run a GUI interface. Please refer to the overview section for instructions on how to login to OnDemand.

Starting a STAR-CCM+ session

Select STAR-CCM+ from the GUIs list of the Interactive Apps drop-down menu, or from the My Interactive Sessions page.

Once you have chosen the resources your job will need, including the version of STAR-CCM+ required, click the Launch to queue the job. Once resources are allocated, click the blue Launch STAR-CCM+ button to connect to your session.

Once connected, the familiar STAR-CCM+ interface is presented, and you will be able to use the allocated resources, and access your research data located on Apocrita.

Do not use NVIDIA MPS

STAR-CCM+ integrates the NVIDIA Multi-Process Service (MPS) but this should not be used on Apocrita as it interferes with correct GPU allocation and prevents other users on the same node from using their assigned GPU(s). Please ensure the "No MPS" checkbox is checked at all times:

Exiting the session

If a session exceeds the requested running time, it will be killed. You can finish your session using one of the following methods:

  • clicking [x] in the upper right corner of the STAR-CCM+ application
  • selecting File -> Exit from the application menus
  • clicking the red Delete button for the relevant session on the My Interactive Sessions page.

After a session ends, the resources will be returned to the cluster queues.
