rhoSimpleFoam & rhoPisoFoam
 
Hi,
could someone tell me what this Error means!
It is very important!
Thank you in advance.

You are dividing by zero in your turbulence model. The problem is that you have specified 0 as internal or boundary value on either k or omega. Use something like 1e-11 instead.

Best regards,

Niels

Thank you Niels!

I did it but problem remains! More ideas please?

Thanks!
