Hi all,

I want to solve a flow of an incompressible fluid through an orifice plate with fluent. but the problem is that it doesn't converge. I have used standard k-e viscous model. What are the problems that may have caused the dis-convergence? here are some info regarding my case:

viscosity: 0.001 kg/m.s
diameter: 0.2 m
distance before the orifice: 1 m
distance after the orifice: 1.5 m
inlet velocity: 0.5 m/s
outlet pressure: atmospheric pressure
