!!The description below is for TriangleMeshReader & needs modification!!
This format is documented at the Triangle homepage. This reader expects to find node information in .node
files and element information in .ele
files. The filename
constructor argument is the stem of the filenames, and so that a reader constructed with filename joe
will look for node and element data in joe.node
and joe.ele
respectively. Node and element attributes are read if present, and can be accessed with the getAttributes()
method of MeshSource.
We have extended the Triangle format to deal with distributed meshes. A TriangleMeshReader is constructed with an MPIComm object, and if that communicator has more than one processor the mesh is assumed to be split into files, one for each processor. Data on mesh "joe" for the nnn-th processor will be found in the files
joe.node.
nnn joe.ele.
nnn joe.par.
nnn .node.
nnn and .ele.
nnn files contain the node and element data for the part of the mesh seen by the nnn-th processor. The node and element numberings given in those two files are local indexes. The .par.
nnn contains node and element ownership information for the part of the mesh seen by the nnn-th processor.
A .par
file is formatted as follows:
rank numProcs
numPoints
ptLID ptGID ptOwnerRank
numElems
elemLID elemGID elemOwnerRank
