PetscQuadratureExpandComposite#
Return a quadrature over the composite element, which has the original quadrature in each subelement
Synopsis#
#include "petscdt.h"
PetscErrorCode PetscQuadratureExpandComposite(PetscQuadrature q, PetscInt numSubelements, const PetscReal v0[], const PetscReal jac[], PetscQuadrature *qref)
Not Collective; No Fortran Support
Input Parameters#
q - The original
PetscQuadraturenumSubelements - The number of subelements the original element is divided into
v0 - An array of the initial points for each subelement
jac - An array of the Jacobian mappings from the reference to each subelement
Output Parameter#
qref - The dimension
Note#
Together v0 and jac define an affine mapping from the original reference element to each subelement
