PetscFECreateByCell

Create a PetscFE for basic FEM computation

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscFECreateByCell(MPI_Comm comm, PetscInt dim, PetscInt Nc, DMPolytopeType ct, const char prefix[], PetscInt qorder, PetscFE *fem)

Collective

Input Parameters

• comm - The MPI comm

• dim - The spatial dimension

• Nc - The number of components

• ct - The celltype of the reference cell

• 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.

Developer Notes

This should be called PetscFECreateDefaultByCell() since it is the extension/replacement for PetscFECreateDefault()

Since this generalizes/replaces PetscFECreateDefault() for different DMPolytopeType its name should be PetscFECreateDefaultByPolytopeType()
