DMSnapToGeomModel#

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 "petscdm.h" 
PetscErrorCode DMSnapToGeomModel(DM dm, PetscInt p, PetscInt dE, const PetscScalar mcoords[], PetscScalar gcoords[])

Not Collective

Input Parameters#

  • dm - The DMPLEX object

  • p - The mesh point

  • dE - The coordinate dimension

  • 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.

The coordinate dimension may be different from the coordinate dimension of the dm, for example if the transformation is extrusion.
