Hi loveni,
Sorry for the delayed response. There may be several reasons for this error. Common reasons for failure in the mesh could be your model running out of memory because of the higher mesh refinement level. You should scope your mesh refinement tool to only the area of interest. Also, check the connection in the model and try to lower the pinball radius in the contact. I think this will help you to resolve the issues.
