Hi Mr. Shah ;
Thank you for the reply.
This video is just an example from Youtube, in the order to give an idea of how I have set my fluid domain and boundaries conditions.
My geometry is a plane into a sphere domain. In the order to save time I have performed an axisymmetric geometry. Computation diverged on FENSAP but easily converged on Fluent.
I am not sure but I think that the mesh is not good ( because of the presence of some small surfaces on my geometry); the question is so: why computation has converged on Fluent?
The error message is: Zero iterations in the iterative solver ( Fensap)
Have you an idea about the reason and solution please (especially for FENSAP)?
Thank you a lot
Sincerely regards
