TgRefiner Class Reference

Detailed Description

Auxilliary data for tet mesh refinement using tetgen.

TgRefiner is used to write the metric files used by TetGen in order to refine an existing tetrahedral mesh so that it complies with criteria which cannot be expressed inside TetGen. In the present form, this class writes mtr files which approximately enforce an edge growth ratio limit.
