Hi all,

 

I am trying to mesh an assembly, in which, one body penetrates into another body. I want to mesh them using 3D tetrahedral element. I first mesh the outer body and then mesh the other body which penetrates the first body. I chose the option 'match existing mesh'. However, the nodes of elements of thees two bodies do not connect with each other. Does anybody know how to mesh this kind of model? Below is the link for downloading my .hm file.

Thank you,
