Detailed Description

template<class T>
class JvarMapIntegratedBCInterface< T >

Interface class ("Veneer") for IntegratedBC to provide a mapping from 'jvar' in computeJacobianBlock into the _coupled_moose_vars array.

This class is useful in conjunction with DerivativeMaterialInterface, where vectors of material property derivatives with respect to all coupled variables (iterating over _coupled_moose_vars array) are generated. The mapping enabled the look up of the correct material property derivatives for the current jvar.

mapJvarToCvar() [1/3]

template<class T >

unsigned int JvarMapInterfaceBase< T >::mapJvarToCvar ( unsigned int  jvar )

inherited

Return index into the _coupled_moose_vars array for a given jvar.

Definition at line 147 of file JvarMapInterface.h.

{
  mooseAssert(jvar < _jvar_max_size,
              "Calling mapJvarToCvar for an invalid Moose variable number. Maybe an AuxVariable?");
  int cit = _jvar_map[jvar];

}

mapJvarToCvar() [2/3]

template<class T >

int JvarMapInterfaceBase< T >::mapJvarToCvar ( unsigned int  jvar, const JvarMap &  jvar_map  )

inherited

Return an index into a specific coupled variable vector for a given jvar.

A negative return value indicates that the jvar value does not point to a variable in the couple variable vector corresponding to the mapped parameter.

Definition at line 159 of file JvarMapInterface.h.

{
  mooseAssert(jvar < _jvar_max_size,
              "Calling mapJvarToCvar for an invalid Moose variable number. Maybe an AuxVariable?");
  return jvar_map[jvar];

mapJvarToCvar() [3/3]

template<class T>

bool JvarMapInterfaceBase< T >::mapJvarToCvar ( unsigned int  jvar, unsigned int &  cvar  )

inherited

Set the cvar value to the mapped jvar value and return true if the mapping exists.

Otherwise return false.

Parameters

[in]	jvar	Variable number passed as argument to computeQpOffDiagJacobian
[out]	cvar	Corresponding index into the _coupled_moose_vars array

Returns

true if the requested variable is coupled, false otherwise
