Hi
How do I write out a marked subdomain to a mesh/meshfunction for a)
plotting and b) to a mesh file. for example:
// Create mesh functions over the cell facets
MeshFunction<std::size_t> sub_domains(mesh, mesh.topology().dim());
// Mark all facets as sub domain 3
sub_domains = 3;
// Mark hole as sub domain 0
Hole hole;
hole.mark(sub_domains, 0);
I'd like to write the new subdomain 'hole' to a mesh, e.g., hole.xml.gz and
also be able to plot it using: plot(hole_mesh);
Thanks,
Gennadiy
