Default grid interfaces in unsteady RANS
Posts: n/a

I'm running a case with a nonconformal grid which means that there are grid interfaces between the different zones. The RANS simulation (using the S-A turbulence model) gives good results for steady flow but crashes for unsteady flow. I'm using Fluent 6.2.16. Does anybody else here have the same problem and knows a solution?

Thanks in advance,
