I am trying to get convergence when using the wet steam model in Fluent. It is a very simple case with steam blowing over a wall set to a low temperature. It is mainly the "wsb" equation that is problematic (going to values of order 1e6). I want to do a low speed case with laminar flow.

Anyone have any ideas what might be wrong? I have tried lowing the CFL number and lowering the under-relaxation factor for the wet steam equation. No success.

Have you used the converged solution for the real gas model (wet steam without condensation) as your initial condition?
