Rotating Shaft FEA Study

Hello all,


I seem to have run into an issue with a FEA study and can't seem to get the correct setup for fixture and load application.  I am hoping someone will provide the much needed feedback!!!




1. Horizontally rotating shaft with both ends supported vertically (not fixed).

2. Vertically downward force acting at the middle of shaft.



ISSUE:     Study fails because of fixture/constraint issues.


I have tried numerous fixture/load combinations but still get a study failure!!! Should I be performing a static study first and then modify to a frequency study? Or is there a another approach?


Thank you and hope to hear back!
