Rigid Body Mesh

Hi everybody

 

I would like to create a rigid mesh on the surface of a body, because i need a rigid

 

body, for which are not calculated stresses neither strains.

 

Could i mesh this surface using 'rigid body mesh' panel in automesh panel?

 

if it is the way, the mesh created will be used just to compute other things like interfaces 

 

reactions or others, and the mesh created will be completely rigid ... i'm i wrong?

 

thanks
