Modal analysis of sheet metal part only shows 0.000 MHz

Hello,

 

I'm trying to do a quick modal analysis on a sheet metal part and the result is alway 0 MHz.  I modeled a tube in the part environment with the same result.  I have also modeled a simple rod and only get 0.00 MHz.  Is there something wrong with Simulation Express or have I done something wrong for 3 different parts?

Are you using ST6 or earlier? If so edit your file properties, units, advanced units and change frequency to hertz. The default is Mhz and with a resolution of 3 decimal places this will in most practical cases give a result of 0.

Mark,

 

I'm running ST7.  That did the trick.  Thanks!
