RSM Problem
 

Hallo, I use model RSM to model turbulence.in multiphasic, one uses Favre's average not yet the Reynolds's average. with the Favre's Favre, a new term appears and it is related to the gradient of pressure.I defined it in udf as term source .¶at 1000 itterats, calculation diverges because of the great difference in pressure in inlet and outlet.¶I want to put Boundary condition at the outlet where the pressure is null; Can you help me please.¶ thank you.¶
