CFD: Inlet BC and problem with undefined variable

Dear CFD users,

I have two questions:

1. Which inlet bc should I use if I know both the mass flow and the pressure? They appear to give different results.

2. I trying to simulate non isothermal turbulent flow using the k-w model but I immediately get the error message of "undefined variable: ep_nn" in a specific domain. Has anyone else encountered this before?

Let me know if you need more information.

Best regards
Philip
