Detailed Description

Abstract parallel finite element space.

Definition at line 28 of file pfespace.hpp.

Constructor & Destructor Documentation

◆ ParFiniteElementSpace() [1/5]

mfem::ParFiniteElementSpace::ParFiniteElementSpace ( const ParFiniteElementSpace orig,
ParMesh pmesh = NULL,
const FiniteElementCollection fec = NULL 
)

Copy constructor: deep copy all data from orig except the ParMesh, the FiniteElementCollection, and some derived data.

If the pmesh or fec poiters are NULL (default), then the new ParFiniteElementSpace will reuse the respective pointers from orig. If any of these pointers is not NULL, the given pointer will be used instead of the one used by orig.

Note
The objects pointed to by the pmesh and fec parameters must be either the same objects as the ones used by orig, or copies of them. Otherwise, the behavior is undefined.
Derived data objects, such as the parallel prolongation and restriction operators, the update operator, and any of the face-neighbor data, will not be copied, even if they are created in the orig object.

Definition at line 28 of file pfespace.cpp.

◆ ParFiniteElementSpace() [2/5]

mfem::ParFiniteElementSpace::ParFiniteElementSpace ( const FiniteElementSpace orig,
ParMesh pmesh,
const FiniteElementCollection fec = NULL 
)

Convert/copy the local (Par)FiniteElementSpace orig to ParFiniteElementSpace: deep copy all data from orig except the Mesh, the FiniteElementCollection, and some derived data.

Definition at line 36 of file pfespace.cpp.

◆ ParFiniteElementSpace() [3/5]

mfem::ParFiniteElementSpace::ParFiniteElementSpace ( ParMesh pm,
const FiniteElementSpace global_fes,
const int *  partitioning,
const FiniteElementCollection f = NULL 
)

Construct the local ParFiniteElementSpace corresponing to the global FE space, global_fes.

The parameter pm is the local ParMesh obtained by decomposing the global Mesh used by global_fes. The array partitioning represents the parallel decomposition - it maps global element ids to MPI ranks. If the FiniteElementCollection, f, is NULL (default), the FE collection used by global_fes will be reused. If f is not NULL, it must be the same as, or a copy of, the FE collection used by global_fes.

Definition at line 44 of file pfespace.cpp.

◆ ParFiniteElementSpace() [4/5]

mfem::ParFiniteElementSpace::ParFiniteElementSpace ( ParMesh pm,
const FiniteElementCollection f,
int  dim = 1,
int  ordering = Ordering::byNODES 
)

Definition at line 60 of file pfespace.cpp.

◆ ParFiniteElementSpace() [5/5]

mfem::ParFiniteElementSpace::ParFiniteElementSpace ( ParMesh pm,
NURBSExtension ext,
const FiniteElementCollection f,
int  dim = 1,
int  ordering = Ordering::byNODES 
)

Construct a NURBS FE space based on the given NURBSExtension, ext.

The parameter ext will be deleted by this constructor, replaced by a ParNURBSExtension owned by the ParFiniteElementSpace.

Note
If the pointer ext is NULL, this constructor is equivalent to the standard constructor with the same arguments minus the NURBSExtension, ext.
