Mesh Adaption
 

Hello to everyone!
I'm trying to model a free surface flow (storm water) on an urban area (buildings),but The solver stopped my simulation after 100 iterations.

Could someone tell me what is wrong in my model:confused:?

Thanks

I noticed that there is no response on this subject in any posts past, what's the problem ?Not even ghorrocks

The error looks pretty obvious to me. You are using mesh refinement and that failed. Try it again without mesh refinement.
