Hey Everybody,

I need some guidance in solving a CFD problem.

The main problem is that as soon as I run the calculation in Fluent, the solution diverges after 10-20 iterations. The parameters for the solution in Fluent are as follows:
(1) Model - Realizable k-epsilon with NWF
(2) Boundry Conditions - Inlet velocity with turbulence intensity of 1% and viscosity ratio of 10 %
AND
Outlet pressure with turbulence intensity of 5% and viscosity ratio of 10 %

(3) Courant no = 50 with HYBRID initialization
(4) Solution Method -
(a) scheme - coupled
(b) gradient - least square cell based
(c) pressure - second order
(d) momentum - second order
(e) turbulence kinetic energy - second order
(f) turbulence dissipation rate - second order



Regards,
