NodeSetsFromSideSetsGenerator

Mesh generator which constructs node sets from side sets

Overview

This MeshGenerator object allows the user to generate a corresponding node set for every side set in the mesh. It does not delete or erase side sets.

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

commentnote

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