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

fem -The PetscFE object

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.
