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 PetscQuadrature

  • numSubelements - 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
