LocalMeshData
(*args)¶ Bases:
dolfin.cpp.common.Variable
This class stores mesh data on a local processor corresponding to a portion of a (larger) global mesh.
Note that the data stored in this class does typically not correspond to a topologically connected mesh; it merely stores a list of vertex coordinates, a list of cell-vertex mappings and a list of global vertex numbers for the locally stored vertices.
It is typically used for parsing meshes in parallel from mesh XML files. After local mesh data has been parsed on each processor, a subsequent repartitioning takes place: first a geometric partitioning of the vertices followed by a redistribution of vertex and cell data, and then a topological partitioning again followed by redistribution of vertex and cell data, at that point corresponding to topologically connected meshes instead of local mesh data.
