Mass Center of a body

      Is it possible to change the mass center of a body without changing the CAD and the material? If it is, how can I do it?

      Thank You.

      Why do you want to deviate the center of mass from true center of mass? You can probably add point mass to the geometry on the side you want to shift the center of mass. In order to keep the total mass same, you may need to decrease the density of material or deal with extra mass in the system.

      But again, can you please explain your requirement in some more details?

      Hi, Aniket!

      I draw a shell car and I have to specify its properties in order to get an accurate analysis, relatable with the specifications of EN 1317. The geometry is not the same but that specifications has to be.

      Regards
