Default Drag and moment coefficients
Posts: n/a
I have the Ansys's Multiphysics package (ICEM-CFD only, I believe).

How do I calculate the drag and moment coefficients?

I tryed to use the INTSRF comand but I can't select the nodes how it's indicated in the manual:

"The INTSRF command (Main Menu> General Postproc> Nodal Calcs> Surface Integrl) allows you to integrate nodal results on a selected surface. You must first select the nodes on the surface where the nodal results are to be integrated."

Thanks a lot.
