Hello all,

I have defined a shell geomtry and setup a composite stackup in acp for a composite structure. At the rear of the structure both surfaces meet to form a solid body.

When trying to merge nodes to allow the two meshes to be simulated as one, I have performed a mesh edit within static structural, but as I am using a structure that was defined through acp, when performing a node merge I can only select geometry from the original acp mesh (the shell structure). Therefore when this merge is performed, the mesh turns itself inside out in the merged region as the nodes from the outer shell are moving inwards (this is depicted below).

Is there any solution to this problem?

You will have to start with the two surfaces that touch each other and build the solid mesh from that in ACP. Make sure you have element sets for regions where you want to merge the nodes. Then you can use node merge in Mechanical from the ACP mesh. Or consider using bonded contacts

Or you can start wth connected surface geometry. Create the solid mesh on both sides of the shared surface by using the proper orientation in ACP. THis way the mesh is already connected in ACP
