	MeshPartitioner (DomainPtrArray_Type domains, ParameterListPtr_Type pL, std::string feType, int dimension)
void	readAndPartition (int volumeID=10)
	Main Function of partitioner. Called with volume ID in order to set in case it is not equal to ten. Always make sure the volumeID corresponds to the highest given flag.
void	setEdgesToSurfaces (int meshNumber)
	Only used in 3D to set the edges as subelements to surfaces.
void	setSurfacesToElements (int meshNumber)
	Setting surfaces, i.e. edges in 2D and triangles in 3D, as subelements to the corresponding elements.
void	partitionMesh (MeshUnstrPtr_Type &mesh, int meshNumber)
	Main function, that reads and partions and distributes the mesh to the different processors. Here all necessary maps and lists are created.

findAndSetSurfacesPartitioned()

template<class SC, class LO, class GO, class NO>

void FEDD::MeshPartitioner< SC, LO, GO, NO >::findAndSetSurfacesPartitioned	(	vec2D_int_Type &	surfElements_vec,
		vec2D_int_Type &	surfElements_vec_unsorted,
		vec_int_Type &	surfElementsFlag_vec,

Finding the surfaces corresponding to a specfic element and then setting subelements.

Function that sets edges (2D) or surfaces(3D) to the corresponding element. It determines for the specific element 'element' if it has a surface with a non volumeflag that can be set as subelement

Here is the call graph for this function:

Here is the caller graph for this function:

setEdgesToSurfaces()

template<class SC, class LO, class GO, class NO>

void FEDD::MeshPartitioner< SC, LO, GO, NO >::setEdgesToSurfaces

(

int

meshNumber

)

Only used in 3D to set the edges as subelements to surfaces.

Function that (addionally) adds edges as subelements in the 3D case. This is relevant when the .mesh file also contains edge information in 3D. Otherwise edges are not set as subelements in 3D.

Here is the call graph for this function:

setSurfacesToElements()

template<class SC, class LO, class GO, class NO>

void FEDD::MeshPartitioner< SC, LO, GO, NO >::setSurfacesToElements

(

int

meshNumber

)

Setting surfaces, i.e. edges in 2D and triangles in 3D, as subelements to the corresponding elements.

Adding surfaces as subelements to the corresponding elements. This adresses surfaces in 3D or edges in 2D. If in the 3D case edges are also part of the .mesh file, they will be added as subelements later.
