In some cases, you may want to get conformal mesh without having to use Shared Topology.
For example, maybe instances are being used to create repetitive copies of the mesh, and you want to get conformal mesh between the copies. Shared Topology could be used within the part that is being copied, but each copy would have to be a unique part. Or, maybe meshing speed is paramount so you want to use parallel part by part meshing and later connect the meshes. There are several mesh-based ways to make the mesh conformal across parts. These include:
Mesh connections: This approach starts from an existing shell mesh and imprints and connects the mesh to make it conformal.
Node merge: After meshing, you can insert a node merge operation to make coincident mesh (nodes close together within a tolerance) conformal. Merge nodes can be used in conjunction with match mesh or contact match mesh controls to make the nodes coincident prior to merging.
