  Hello dear
  When we are using three or more different models ( different trees) and combine them into one for analyses, connection (or contact) generate between them.

  nCheck help doc link: Limitations and Restrictions for Model Assembly (ansys.com)nWhen you assemble rigid body systems or systems that include rigid bodies, Mechanical may require you to remesh the rigid bodies if the application detects new contact conditions on the rigid bodies. If this is the case, the application sets the Read Only property on the Mesh object to No and also cleans any imported mesh-based Named Selections. These objects need to be re-scoped. The Mesh object property, Read Only is set to No when importing rigid bodies or rigid body systems from Mechanical Model and/or analysis systems. Note that it is not possible to remesh (Read Only cannot be set to No) when assembling upstream sources from External Model or ACP, so contact conditions with rigid bodies are not allowed in such cases if remeshing is required.nnYour assembly has ACP Pre. So you will not be able to remesh rigid bodies. See if you can use flexible bodies instead of rigid and define a material with very high stiffnessn
