epsilon divergence
 
I am trying to simulate the airflow in a furnished room with ventilation using the standard k-esp. The problem I encounter is that after some iterations epsilon diverges. I have tried modifying the urfs, applying non-iter-time advancement, even using only first order discretization just to tackle that...but nothing. Can anyone help me?

Thanks a lot, Spyros

Try to adjust the Relaxation Factor.

Thanks Peggy for replying, it seems that the problem was in the initial conditions for kappa and epsilon in the inlets. I have also switched to RNG (it does not overestimate kappa).

Take care, Spyros
