Member Function Documentation

computeValue()

void NodalNumIntactBondsPD::computeValue ( unsigned int  id, dof_id_type  dof  )

overridevirtual

Function to assemble elemental quantities to nodal AuxVariable at a material point.

Parameters

id	The local index of element node (either 1 or 2 for Edge2 element)
dof	The global DOF of element node

Returns

The computed value for the node

Implements NodalAuxVariableUserObjectBasePD.
