Detailed Description

Information for allocating entities of an unstructured mesh.

This class allows specifying the cells that will be added during the initial mesh allocation. You must call setMeshDimension() to specify the mesh dimension, then call addCell() for each cell you wish to add. Once all cells have been added, you must call allocateMesh().

_internal()

UnstructuredMeshAllocateBuildInfoInternal * Arcane::UnstructuredMeshAllocateBuildInfo::_internal

(

Internal part reserved for Arcane.

addCell()

void Arcane::UnstructuredMeshAllocateBuildInfo::addCell	(	ItemTypeId	type_id,
		Int64	cell_uid,
		SmallSpan< const Int64 >	nodes_uid )

Adds a cell to the mesh.

allocateMesh()

void Arcane::UnstructuredMeshAllocateBuildInfo::allocateMesh

(

)

Allocates the mesh with the cells added during the call to addCell().

This method is collective.

preAllocate()

void Arcane::UnstructuredMeshAllocateBuildInfo::preAllocate	(	Int32	nb_cell,
		Int64	nb_connectivity_node )

Pre-allocate the memory.

Pre-allocates the arrays containing the connectivity to hold nb_cell cells and nb_connectivity_node for the list of cell nodes.

This method is optional and is only useful for optimizing memory management.

For example, if we know that our mesh will contain 300 quadrangles then we can use preAllocate(300,300*4).

setMeshDimension()

void Arcane::UnstructuredMeshAllocateBuildInfo::setMeshDimension

(

Int32

v

)

Sets the mesh dimension.
