XFEMCutPlaneAux

Computes the normal and origin of a cutting plane for each partial element.

Description

The MOOSE XFEM implementation uses the phantom node technique, in which elements traversed by a discontinuity are split into two partial elements, each containing physical and non-physical material. The XFEMCutPlaneAux output is used in XFEM Paraview Plugin (MooseXfemClip) to define a cutting plane to cut off the non-physical portions of partial elements. It can be automatically added when output_cut_plane = true in XFEM block.
