Mesh.get_free_edges_mesh(compact=True)#

Return a Mesh with the free edges.

Free edges are edges that are only connected to a single element.

Parameters#

compact: bool: If True (default), the returned Mesh will be compacted. If False, the returned Mesh will contain all the nodes present in the input Mesh.

Returns#

Mesh: A Mesh containing the free edges of the input Mesh. Free edges are edges that are only connected to a single element. If the input Mesh has property numbers, the edge elements inherit the property of the element to which they belong.
