Unsteady SIMPLE
 

Hi,

I have finished my unstructured steady finite volume SIMPLE program for collocated grids and now I am trying to get it unsteady.

Well I have discretized the temporal terms but my question is about convergence. For each time step I should solve the momentum and the pressure equation for a couple times until convergence (or a given tolerance) to go for the next time step. I have looking for it in the forum and in a couple books but I am not able to find it.


Could anyone help me and tell my which paramater should I focus and the tolerance that I should give it?


Regards

Any help please?
