MFX: weired force transfer from cfx to ansys

October 6, 2006, 01:58

I'm using cfx 10.0 and ansys multiphysics 10.0 to simulate a fluid-structure interaction problem. The model is very simple, just a flat panel with fluid flows above it. cfx run in transient mode, ansys run in steady mode.

cfx solver run first and then ansys. after first cfx run, the pressure on panel should be 1 atm (101325Pa), and force 101325N (the panel is 1x1 in gemotry), it does right. then the pressure load tranftered to ansys, but after reviewing ansys output file, I find the force is 0.10133E+7, which is 10 times to cfx load. It's WRONG, because the load relax factor has been set to 1, these two force should be equal.

has anyone found this problem?

Looking under the CFX technotes at example they given.

I can't access to CFX community site now. Would you send me a copy of that example?
