How to check at how many iteraions starccm+ converges
 
Hi,

I would like to know how to check the number of iterations sarccm+ converges at each time step. Can anyone help me?


Thanks,

LP

I don't really understand what do you mean, the default is to set how many number iteration per-time step.
You can also set your own criterion. You can read the manual Running > Setting up Stopping Criteria.

Look at the residuals. Usually it's good when the residuals drop for two or three orders of magnitude in each time step. But it also depends a little on the case...
