Hello
I'm doing transient simulations of a 3D bubble column on CFX using Euler-Euler approach. For the boundary condition, I add an air freeboard region on top the liquid phase and I set correctly the hydrostatic pressure. It works great in the serial calculation but It doesn't even start in the parallel calculation. I always get this error :
+--------------------------------------------------------------------+
| ERROR #004100018 has occurred in subroutine FINMES. |
| Message: |
| Fatal overflow in linear solver. |
+--------------------------------------------------------------------+
map size mismatch; abort
: File exists

I know that adding the air freeboard region is the cause of the error and I saw in the cfx guide that I can ignore it and it works for serial calculation but how can I make it work for parallel calculation and can anyone explain why it doesn't work??
