Member Function Documentation

mapJvarToCvar() [1/2]

template<class T >

unsigned int JvarMapInterfaceBase< T >::mapJvarToCvar

(

unsigned int

jvar

)

Return index into the _coupled_moose_vars array for a given jvar.

Definition at line 109 of file JvarMapInterface.h.

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

  mooseAssert(cit >= 0, "Calling mapJvarToCvar for a variable not coupled to this kernel.");
  return cit;
}

mapJvarToCvar() [2/2]

template<class T>

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

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
