Use a Join Entities node () to join adjacent geometric entities in an imported mesh.

To add a Join Entities node, right-click a 2D or 3D mesh node and select Join Entities. Then use the following sections to specify the geometric entities to join:

Define the geometric entities that you want to join. You choose the geometric entity level from the Geometric entity level list: Choose Domain, Boundary, or Edge to specify the domains, boundaries, or edges, respectively, that you want to join. Use All domains, All boundaries, or All edges to select all entities of the specified dimension.

Select the Join adjacent lower dimensional entities check box to also join the adjacent entities of lower dimensions (boundaries and edges for joined domains, for example).
