MortarFrictionalPressureVectorAux
Description
The MortarFrictionalPressureVectorAux outputs the frictional pressure vector components using information from the mortar contact solution and its geometry. Nodal information is used to associate the two frictional Lagrange's multiplier vectors in three-dimensions with their corresponding tangent vectors generated at the time the mortar segment mesh is generated. This auxiliary kernel is automatically included in the ContactAction when the user selects three-dimensional, frictional mortar contact. The computation of the frictional pressure vector can be expressed as:
where denotes the frictional pressure vector, and are two frictional Lagrange's multipliers, and and are two mutually perpendicular tangent vectors. Note that the directions and need not be aligned with global axes. This object is an AuxKernel, and is used only for the purpose of output. Note that the Contact action sets this object up automatically, so it is typically not necessary to include this in an input file.
