Guys, it seems I am having trouble to make it converge.

simulation of unsteady flow, LES

summary: I have some doubt with the old mesh, So I generate another mesh which might be exactly the same as the old one. Then I use the interpolation file from the old case to initialize the new case, start simulation, and now I am having trouble to make it converge fast in every time step.

How can I set the convergence criteria properly when the initialization is too good?

Thanks a lot!

Hi ivanbuz,
I dont think that Initiation has much response on your simulation!!! I think initiation is how we can guess the final value!!! The value is depend on us!!!
there is no wrong and right value!!
hope it helps
