**tet_refinement#

Description#

This mesher is used to refine a zone of a tetrahedral mesh defined by a given set of nodes.

Syntax#

**tet_refinement \(~\,\) *nset node_set \(~\,\) [ *quad ] \(~\,\) [ *conserve_nsets]

*nset

The name of the nset defining the region to be refined.

*quad

A flag to set quadratic mesh.

conserve_nsets

Include newly added nodes in the same node set as their adjacent nodes already in that set. By default, node sets remains exactly the same as in the initial mesh.
