SideSetsFromNodeSetsGenerator

Mesh generator which constructs side sets from node sets

Overview

This MeshGenerator object allows the user to make matching side sets for every existing node set. It does not delete or erase the original node sets in the process. A side may only be created from several nodes if the nodes are forming a side of an element.

For example, for a 2D element, nodes from the node set must be on the two edges of a vertex of an element to make this vertex be part of the created sideset. For a 3D hexagonal element, the four nodes on the corners of a face of an element must be part of the original node set to make the quadrilateral face be part of the created side set.

In the current implementation, this operation indiscriminately converts all node sets into side sets.

note

This operation can also be performed automatically at the end of the mesh generation process if construct_side_list_from_node_list = true in the [Mesh] block.
