XFEMMaterialTensorMarkerUserObject

under construction:Undocumented Class

The XFEMMaterialTensorMarkerUserObject has not been documented, if you would like to contribute to MOOSE by writing documentation, please see Documenting MOOSE. The content contained on this page explains the typical documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.
