Transient Simulation problem of a sealed geometry
 

Hi folks,

According to my dissertation I'm trying to model some sort of condensation. I've now been given a wall condensation example by ANSYS support for a very simple case shown in the picture. Running the initial example either steady state or time dependent does not make any problems.

However, as I'm trying to get rid of the inlets and outlets to get a flow purely driven by gravity it is not letting me simulate more than a certain time and I can't manage to solve this problem. Could this have to do with the fact that the bottom wall is set to a temperature while the top and right wall is adiabatic and the rest is set to symmetry?

Thx in advance, your help is much appreciated.
