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#

Note#

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.
