I have solved a problem using CFX 12.0, now I want make the mesh a little finner in CFX-mesh, but each time I do it, my problem diverges as I try to solve it, i.e. the CFX-solver faces with an error after 50 timesteps.
help me with understanding why such problem occurs. Thank you. |

Finer mesh are more numerically unstable. There are tips on convergence on the documentation, some more here http://www.cfd-online.com/Wiki/Ansys...gence_criteria
