Reply To: Multiphase model doesn’t give good results

Hi Rob, I've run again the simulation these are the residuals after 1250 iterations:

And these are the residuals after adding 600 iteations on top:

I ran the first 1250 itrations in batch mode through Workbench in Optislang and the other 600 manually by opening the workbench file and changing the number of iterations. 

The UDS are for the mean age of air and for the PLI calculation, I've got a spike in them as well (these are reported in the same cell zone of my domain and on the mixture phase). In the first two iteration I get the message:         Stabilizing uds-0 to enhance linear solver robustness.
        Stabilizing uds-1 to enhance linear solver robustness. and after this the values seem to be okay.
