PETSc version 3.16.6

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

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 Parameters

dim

- The dimension

Note: Together v0 and jac define an affine mapping from the original reference element to each subelement
