How can I change the phase of a modeshape result?

Hi,

I have done the modal analysis of rectangular plates. Each plate has same length and breadth but has holes at different locations. I want to compare the modeshapes of these plates by overlaying them.

When I overlay two h3d files, they appear with a 180 degree phase shift with respect to each other, i.e. the crest of one plate meets the trough of the other plate for every mode. How can I change the phase of one of the plates by 180 degrees?

Or is there any other way to correct this?

 

regards,

Vachan

    Hi,

     

    Try to change the 'Deformed shape' scale factor as following: one = value; second = -value

     

    Best Regards,
