Hi, 

 

Can we measure the moment of inertia of my model in Hypermesh or Hypercrash and, of course, from a local coordinate system? Because I know the MASS tool in Hypercrash, but it is measuring from the global system.

 

I want to measure it from a local system of coordinates.

 

Thanks!

    Hi

    In hypermesh you can use command hm_getmoi

    Ex:

     

    *createmark elems 1 displayed

    hm_getmoi elems 1 2 $origin_node_id 2 $local_system_id 0 0
