PetscFECreateDefault#

Create a PetscFE for basic FEM computation

Synopsis#

#include "petscfe.h" 
PetscErrorCode PetscFECreateDefault(MPI_Comm comm, PetscInt dim, PetscInt Nc, PetscBool isSimplex, const char prefix[], 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

  • prefix - The options prefix, or NULL

  • qorder - The quadrature order or PETSC_DETERMINE to use PetscSpace polynomial degree

Output Parameter#

  • fem - The PetscFE object

Note#

Each subobject is SetFromOption() during creation, so that the object may be customized from the command line, using the prefix specified above. See the links below for the particular options available.
