PetscFECreateLagrange
Create a PetscFE for the basic Lagrange space of degree k
Synopsis
#include "petscfe.h"
PetscErrorCode PetscFECreateLagrange(MPI_Comm comm, PetscInt dim, PetscInt Nc, PetscBool isSimplex, PetscInt k, PetscInt qorder, PetscFE *fem)
Collective
Input Parameters
| comm | - The MPI comm
|
| dim | - The spatial dimension
|
| Nc | - The number of components
|
| isSimplex | - Flag for simplex reference cell, otherwise its a tensor product
|
| k | - The degree k of the space
|
| qorder | - The quadrature order or PETSC_DETERMINE to use PetscSpace polynomial degree
|
Output Parameter
Notes
For simplices, this element is the space of maximum polynomial degree k, otherwise it is a tensor product of 1D polynomials, each with maximal degree k.
