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())
