DMPlexComputeProjection3Dto1D#

Rewrite coordinates to be the 1D projection of the 3D coordinates

Synopsis#

#include "petscdmplex.h"   
#include "petscfe.h"       
PetscErrorCode DMPlexComputeProjection3Dto1D(PetscScalar coords[], PetscReal R[])

Not Collective

Input/Output Parameter#

  • coords - The coordinates of a segment; on output, the new y-coordinate, and 0 for x and z

Output Parameter#

  • R - The rotation which accomplishes the projection

Note#

This uses the basis completion described by Frisvad [Fri12]
