Impeller Analysis Problems

Question asked by 1-TDH7JX on Oct 26, 2010

I'm relatively new to Simulation and having trouble setting up an analysis on an impeller component.  I would like to approximate the component stresses taking into account both the centrifugal inertia loads plus a net pressure reaction on the blades.  I have been able to set up two individual studies  - one with centrifugal loads acting alone, and one with pressure loads acting alone.  I get simulation failures, however, when trying to combine the two loading conditions into one study.  Anyone have any suggestions on how best to setup this type of analysis to take into account both loading effects?
