arslandogukanitu is on a distinguished road
I have an analysis which is laminar, 3D, conjugate heat transfer and related to udf. I set inlet velocity and temperature ,and heat flux fr wall bottom. Without udf code, the analysis can be converge but while i am using udf the analysis was divergence. By the way, my udf code is valid because in previous cases, this code was used and it worked.

I have four different mesh for one model. Model which have the finnest cant be converged but other ones which have more coarse mesh can be easily converged.
