Getting to the Fundamentals of a Modal Analysis in Nastran In-CAD

[@WyzaNagui]

Are you suppose to constrain the part in modal analysis?

[@binaybehera1336]

Good for CAE engineers and CAE beginners

I get zero percent modal effective mass on a thin cylindrical stack. Any ideas why ?

[@jmkubli]

I would start off with the simplest and that would be to make sure the assigned material has a density.

may be you have rigid body modes

Thank u so much for this such a great video..it's helpful of many Engineering students......sir..... actually I'm doing a electric go kart..so I have problem with simulation..can I have u r contact details sir .??
