Detailed Description

File containing a utility to reorder a mesh.

This utility contains a method to reorder the meshes reducing the fill-in of the matrix, and a method to create a different marker on a region of a mesh. In particular this region is identified by a marker of another mesh that shares an interface (e.g. solid interface and fluid edges in FSI).

For instance suppose that you have marker=20 on the fluid 'edges' and on the solid mesh you have just different markers for the internal and external walls, then using this test you can create a marker '30' on the solid mesh whenever the corresponding marker on the fluid mesh is '20', and rewrite the mesh.

usage: test_meshReorder -o mesh_output.mesh

without the options -o or –output the output mesh can be specified from this data file. Otherwise the mesh will be written in a file 'mesh'.

the first mesh is the one reordered. The second mesh is the one where the new marker is added (not read when create_edge=false).
