[Gmsh] bandwidth optimization

[Filipe Silveira]

Please, I'd like to confirm if is there any mean to realize a  
bandwidth optimization directly through gmsh. The meshes I've been  
generated has too big stiffness matrix, and it's hard to run.
I've found this information (link below), but it didn't work...

Thanks in advance,
