DMPlexSnapToGeomModel

Given a coordinate point 'mcoords' on the mesh point 'p', return the closest coordinate point 'gcoords' on the geometry model associated with that point.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexSnapToGeomModel(DM dm, PetscInt p, const PetscScalar mcoords[], PetscScalar gcoords[])
Not collective

Input Parameters

dm - The DMPlex object
p - The mesh point
mcoords - A coordinate point lying on the mesh point

Output Parameter

gcoords - The closest coordinate point on the geometry model associated with 'p' to the given point

Note: Returns the original coordinates if no geometry model is found. Right now the only supported geometry model is EGADS.
