i m getting high skewness values in my jet impingement model around 0.84. i m doing the simulation in transient mode with courant no. 50 for 11.5 lakh cells on k-omega model (SST). tried to refine the mesh many times but still no difference. Can anyone help me to remove this error.

A courant number of 50 is way too high. You shouldn't go over 3-4 at most.

The rest of this could be code specific and you should probably ask those questions in that specific subforum for it.
