problem in convergence; buoyantBoussinesqSimpleFoam
 

Hi everybody,

I'm using buoyantBoussinesqSimpleFoam. my results are very good till it iterate 25000 and I check its validation. but when I choose the end time equal 70000, some oscillation occur in my results. one of my wall is inletOutlet.
anybody knows why this happened?

thank you.
