sizeNodalProperties()

void PorousFlowMaterial::sizeNodalProperties ( )

protectedinherited

Resizes properties to be equal to max(number of nodes, number of quadpoints) in the current element.

Definition at line 79 of file PorousFlowMaterial.C.

{
  /*
   * For nodal materials, the Properties should be sized as the maximum of
   * the number of nodes and the number of quadpoints.
   * We only actually need "number of nodes" pieces of information, which are
   * computed by computeProperties(), so the n_points - _current_elem->n_nodes()
   * elements at the end of the std::vector will always be zero, but they
   * are needed because MOOSE does copy operations (etc) that assumes that
   * the std::vector is sized to number of quadpoints.
   *
   * On boundary materials, the number of nodes may be larger than the number of
   * qps on the face of the element, in which case the remaining entries in the
   * material properties storage will be zero.
