MeshGetBoundaryStart

 Retrieves the canonical node number of the first node on the specified boundary.

Synopsis

#include "mesh.h" 
int MeshGetBoundaryStart(Mesh mesh, int boundary, PetscTruth ghost, int *node)
Not collective

Input Parameters

mesh - The mesh
boundary - The boundary marker
ghost - Flag for including ghost nodes

Output Parameter

node -The canonical node number

Note

This is typically used as an iteration construct with MeshGetBoundaryNext(),

for example:



MeshGetBoundaryStart(mesh, OUTER_BD, &node, PETSC_FALSE);



while (node >= 0) {



  PetscPrintf(PETSC_COMM_SELF, "I have boundary node %d\n", node);



  MeshGetBoundaryNext(mesh, OUTER_BD, &node, PETSC_FALSE);



}
