computeValue()

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

overridevirtualinherited

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.

  Real dg_vol_frac = _pdmesh.getDefGradVolFraction(_current_elem->node_id(id), id_j_in_i);
 
  // gather volume weighted contribution only if the bond is active
  if (_bond_status_var->getElementalValue(_current_elem) > 0.5)

dg_vol_frac	volume fraction of deformation gradient approximation to its summation at a node

Returns

What the function returns (if it returns anything)
