Hi,

I am facing problem in CFX-Simulation. Case is regarding Rotor-stator-Radial-splitter(Core and Bypass) case.

Problem : point flow exception: overflow.

I have checked with the BC'S and Initialisation. Could you please suggest?

Regards, Jwala.

Hi,

Your simulation is diverging. Read the section in the documentation about "obtaining convergence". This may also help: http://www.cfd-online.com/Wiki/Ansys...gence_criteria

Under solver setting reduce your time step. It works for me when I do that!

Hi,

Thanks for the suggestion. I had done the same before but the convergence is not good.
