In rigid body dynamics (multi-body dynamics), Library is the default Material Input Type for a body.
Users can choose a material from the Material Type list.
If you need a material library that is not included in the list, there are2 ways to use the properties of a new material.
(Since you only need density for a rigid body analysis.)
1) Density
Change the Material Input Type to Density, then input the new density value.
2) User Material Property
On the SubEntity tab, in the Property group, register the properties of a new material.
The new material is added to the bottom of the Material Type list. The properties of this material can then be used as library.
(Young's modulus and Poisson's ratio are not used, only density is used.)
