Detailed Description

template<typename MeshType>
class LifeV::MeshPartBuilder< MeshType >

Class that builds a mesh part, after the graph has been partitioned.

Author: Radu Popescu radu..nosp@m.pope.nosp@m.scu@e.nosp@m.pfl..nosp@m.ch

This class is used as a component for the MeshPartitionTool class. When an object of class MeshPartBuilder is instantiated it holds pointer to the global uncut mesh.

The only public method that this class implements is a run method, which takes a vector of element IDs which corespond to a mesh part and builds a RegionMesh object with this elements.

Here is the caller graph for this function:

◆ markEntityOwnership()

void markEntityOwnership ( const entityPID_Type & entityPID )

private

Mark entity ownership.

Mark all owned entities in the partition with EntityFlag::OWNED to properly build map members in DOF::GlobalElements().
