TagMatrixAux(const InputParameters &parameters)
Definition: TagMatrixAux.C:27
The main MOOSE class responsible for handling user-defined parameters in almost every MOOSE system...
virtual Real computeValue() override
Compute and return the value of the aux variable.

registerMooseObject("MooseApp", TagMatrixAux)
const VariableValue & _v
Definition: TagMatrixAux.h:33
For visualization or other purposes, the diagnal of the matrix of a tag is extracted, and nodal values are assigned by using the matrix diagnal values.
Definition: TagMatrixAux.h:24
void addRequiredCoupledVar(const std::string &name, const std::string &doc_string)
This method adds a coupled variable name pair.
unsigned int _qp
Quadrature point index.
Definition: AuxKernel.h:219
void addClassDescription(const std::string &doc_string)
This method adds a description of the class that will be displayed in the input file syntax dump...
void addParam(const std::string &name, const S &value, const std::string &doc_string)
These methods add an option parameter and a documentation string to the InputParameters object...
Base class for creating new auxiliary kernels and auxiliary boundary conditions.
