A simple question!
 
Hello everyone:

I am using cfx-tascflow 2.10 to solve a very simple example(on axis compressor).The boundary conditions come from the experimental data. I found it was difficult to converge when the mesh (near the blade surface)become dense and the grid size exceeded 400000. I think some parameters set maybe undesirable. But I doní»t know the actual reasons.

Thanks!

If you can get converged solution at coarse mesh.You can do at other circumstance. You can try set the Dtime smaller and change initial.
