virtual double Feel::MeshBase::measure ( ) const

pure virtual

Returns:

the measure of the mesh

inline

Returns the number of partitions.

virtual size_type Feel::MeshBase::numElements ( ) const

copy operator

virtual void Feel::MeshBase::partition ( const uint16_type  n_parts )

pure virtual

Call the default partitioner (currently metis_partition()).

virtual void Feel::MeshBase::renumber ( )

protectedpure virtual

After loading/defining a mesh, we want to have as much locality as possible (elements/faces/nodes to be contiguous). In order to do that the mesh elements/faces/nodes are renumbered. That will be then most helpful when generating the Dof table. This procedure should work also with comm().size() == 1

Implemented in Feel::Mesh3D< Shape >, Feel::Mesh2D< Shape >, Feel::Mesh1D< Shape >, and Feel::Mesh0D< Shape >.
