How to split solid bodies?

[hao1996]

When I use an imported mesh from Hypermesh in Ansys Mechnical, the imported geometries are set as one solidbody like the following picture:

When I need to set one of these bodies to rigid body, the error of "All bodies under this part must have the same setting for stiffness behavior" occurs. So, how can I split these bodies into seperate ones?

Hello,

All bodies in a body group (of a multibody part) must have the same Stiffness Behavior. When Stiffness Behavior is Rigid, the body group acts as one rigid mass regardless of whether or not the underlying bodies are topologically connected (via shared topology).

In addition please refer to the following links:
