Hi all,

I am dealing with a conjugate heat transfer problem for electronics cooling in a very small domain (compartment) in FLUENT, with quite a complex geometry, and I am a little bit stagnated.

I have been fighting with the mesh for a long time, and I think all problems related with skewness and quality are already solved. Also interfaces are correct. Still, I am having troubles for convergence.

I suspect the problem is, as it is such a small domain, that a very high gradients for temperature and turbulence variables can be found at the outlet. However, I would like to avoid to extrude it farther out of the compartment...

My outlet is, in a first approuch, a pressure-outlet.

¿Any idea on how could I treat this situation?

I would appreciate very much any guess.
