Integer Arcane::MshParallelMeshReader::_readElementsFromFile ( )

private

Reading of elements (cells, faces, ...).

Here is the format description:

* $Elements
*   numEntityBlocks(size_t) numElements(size_t)
*     minElementTag(size_t) maxElementTag(size_t)
*   entityDim(int) entityTag(int) elementType(int; see below)
*     numElementsInBlock(size_t)
*     elementTag(size_t) nodeTag(size_t) ...
*     ...
*   ...
* $EndElements
*

In version 4, elements are sorted by type (eItemKind). Each entity block may have a different dimension. There is no mesh dimension associated with it. Therefore, we consider the dimension of the mesh to be the highest dimension of the blocks we read. This also means that we are forced to read all blocks before we can know the mesh dimension.

In parallel, each block is distributed across the ranks in m_parts_rank.

Returns: the mesh dimension.

void Arcane::MshParallelMeshReader::_setNodesCoordinates ( )

private

Positions the node coordinates.

The list is distributed across the processors of the ranks in m_parts_rank. We loop through the ranks in this list, and each rank sends to the others the list of coordinates of the nodes it contains. Each rank checks if any nodes from this list belong to it, and if so, positions them.

Note: This algorithm sends all nodes piece by piece and is therefore not truly parallel in execution time. This could be improved if we knew the range of uniqueIds() for each part and thus directly request the desired coordinates from the concerned rank.
