solver convergence
 

I am running a problem related valve with tetrahedral elements. Inlet boundary is velocity and pressure boundary is 0 pa while reference pressure is 101235 pa. With default values, the star solver oscillates pressure equation residuals. The default value of relaxation paratmeter is 3 and tried with 2.5 or 3.5 but no improvements. Can any star-cd user suggest a hint to overcome this convergence problem.

Re: solver convergence
 

you mean default value by pressure 0.3. Suggest to increase the number of sweeps to 5000.
