Hi,

The default density of ChBody is uniform. But I want to change it by changing its inertia and CoG.  Is there a way to do it?

Thanks,
Qihan

Qihan,

Could you please check out the usage of ChBodyAuxRef - https://api.projectchrono.org/classchrono_1_1_ch_body_aux_ref.html

You should be able to find functions - SetInertiaXX and SetFrame_COG_to_REF.

Anyone please feel free to correct me or add info.

Jason

Thanks for your reply.
It works.
I usually use ChBodyAuxRef in the triangle mesh body. But now I found out it can also be applied to ChBodyEasyBox, ChBodyEasySphere, etc.

Thanks,
Qihan
