Different results on different computers?

[pumpkinseed]

I did modal analysis on my laptop...that gives me 0 frequency for the first three modes.I ran the same analysis on another computer and I get first frequency as 5.8Hz..and so on....why I am getting different results on different computers?
thanks

Are you sure you're using the SAME database? You have rigid body motion occurring. It seems likely that something is different in your constraints or model.

If you're positive that everything is the same then I would contact your friendly local Ansys support. I'd be really surprised if there wasn't something different but you never know...Ansys does have a few bugs. Good luck.
