Im doing a two mixing flow on intermixingfoam , it is a RAS model but when it runs, didn't solve any iteration and tells me that initial residual to pcorr is 0 and the final residual is 0 to...
I already searched a lot about this error but i couldn't be able to solve it, here is what the log file says :

No finite volume options present
GAMG: Solving for pcorr, Initial residual = 0, Final residual = 0, No Iterations 0
time step continuity errors : sum local = 0, global = 0, cumulative = 0

I would be greatful if someone could help me.
Thank you

Hi,

Still difficult to diagnose the matter.

Could you please provide sufficient detail for us to understand your problem?

Ok it was resolved by using wall functions on Epsilon Kappa and nut variables, i think the problem was that because of not using wall functions on boundary conditions, it was having trouble solving the equations of k-e and nut ,
Thank you a lot for the reply!!!
