GridCalcBoundaryElementMatIndices

This function calculates the global row and column indices for a particular boundary element using alternate variable orderings.

Synopsis

#include "grid.h" 
int GridCalcBoundaryElementMatIndices(Grid grid, int bd, int edge, int midNode, VarOrdering sOrder, VarOrdering tOrder,
                                      PetscTruth useLocal, ElementMat mat)

Not collective

Input Parameters

	grid	- The Grid
	bd	- The boundary index
	edge	- The canonical edge number
	midNode	- [Optional] The canonical node number of the midnode on the edge, or -1 if none exists
	sOrder	- The global variable ordering for the shape functions
	tOrder	- The global variable ordering for the test functions
	useLocal	- The flag for local numbering of ghost nodes

Output Parameter

mat -The element matrix

Note

The boundary is specified by its index, not marker. Use MeshGetBoundaryIndex() to retrieve this from the marker.
