DMMoabPToRMapping#
Compute the mapping from the physical coordinate system for a given element to the canonical reference element. In addition to finding the inverse mapping evaluation through Newton iteration, the basis function at the parametric point is also evaluated optionally.

PetscErrorCode DMMoabPToRMapping(const PetscInt dim, const PetscInt nverts, const PetscReal *coordinates, const PetscReal *xphy, PetscReal *natparam, PetscReal *phi)
Input Parameters#
PetscInt dim - the element dimension (1=EDGE, 2=QUAD/TRI, 3=HEX/TET)
PetscInt nverts - the number of vertices in the physical element
PetscReal coordinates - the coordinates of vertices in the physical element
PetscReal[3] xphy - the coordinates of physical point for which natural coordinates (in reference frame) are sought
Output Parameters#
PetscReal[3] natparam - the natural coordinates (in reference frame) corresponding to xphy
PetscReal[nverts] phi - the basis functions evaluated at the natural coordinates (natparam)
