  Hi
  I am trying to calculate the CPU time that it takes for running fluent simulations on HPC. I have 2 meshes one fine and one coarse, i want to calculate the time it takes to run the same problem on the 2 meshes and compare. How can i do that?
  thanks

  Do I need to set this command in the journal file while submitting the job on HPC? And the after the simulation has run should i open the dat file in fluent and use the same command on the console?

    Yes, you can use this command in the end of your journal (before closing Fluent) and it will print out the details in the transcript (.trn) associated with the run.
