I am having a tube which has one hole(inlet) at the top and 45 holes(pressure outelt) in the bottom. The model doesnt seem to converge. The flow is laminar when it enters the inlet. I am using segregated-laminar model. Please tell me what kind of discretization schemes and underrelaxation factors shud I use??
Re: Convergence problem
If at first, it doesn't converge, use very low under-relaxation factors, say 0.2~0.3, for example. Then gradually up the values as your results begin to converge.
