DMPlexReferenceToCoordinates

Map references coordinates to coordinates in the mesh for a single element map.

Synopsis

#include "petscdmplex.h"   
#include "petscfe.h"       
PetscErrorCode DMPlexReferenceToCoordinates(DM dm, PetscInt cell, PetscInt numPoints, const PetscReal refCoords[], PetscReal realCoords[])

Not Collective

Input Parameters

• dm - The mesh, with coordinate maps defined either by a PetscDS for the coordinate DM (see DMGetCoordinateDM()) or implicitly by the coordinates of the corner vertices of the cell: as an affine map for simplicial elements, or as a multilinear map for tensor-product elements

• cell - the cell whose map is used.

• numPoints - the number of points to locate

• refCoords - (numPoints x dimension) array of reference coordinates (see DMGetDimension())

Output Parameter

• realCoords - (numPoints x coordinate dimension) array of coordinates (see DMGetCoordinateDim())
