Constructor & Destructor Documentation

mfem::ParMesh::ParMesh ( )
inlineprotected

Definition at line 31 of file pmesh.hpp.

mfem::ParMesh::ParMesh ( const ParNCMesh pncmesh)
protected

Create from a nonconforming mesh.

Definition at line 672 of file pmesh.cpp.

mfem::ParMesh::ParMesh ( const ParMesh pmesh,
bool  copy_nodes = true 
)
explicit

Copy constructor. Performs a deep copy of (almost) all data, so that the source mesh can be modified (e.g. deleted, refined) without affecting the new mesh. If 'copy_nodes' is false, use a shallow (pointer) copy for the nodes, if present.

Definition at line 28 of file pmesh.cpp.

mfem::ParMesh::ParMesh ( MPI_Comm  comm,
Mesh mesh,
int *  partitioning_ = NULL,
int  part_method = 1 
)

Definition at line 83 of file pmesh.cpp.

mfem::ParMesh::ParMesh ( MPI_Comm  comm,
std::istream &  input 
)

Read a parallel mesh, each MPI rank from its own file/stream.

Definition at line 683 of file pmesh.cpp.

mfem::ParMesh::ParMesh ( ParMesh orig_mesh,
int  ref_factor,
int  ref_type 
)

Create a uniformly refined (by any factor) version of orig_mesh.

Parameters
[in]orig_meshThe starting coarse mesh.
[in]ref_factorThe refinement factor, an integer > 1.
[in]ref_typeSpecify the positions of the new vertices. The options are BasisType::ClosedUniform or BasisType::GaussLobatto.

The refinement data which can be accessed with GetRefinementTransforms() is set to reflect the performed refinements.

Note
The constructed ParMesh is linear, i.e. it does not have nodes.
