[Paraview] ENC: RES: one global structure

[Renato N. Elias]

Hi Fabian,

My Fortran routines to write Ensight files in binary format may be found in
http://www.nacad.ufrj.br/~rnelias/paraview (EnsightRoutines.zip). You'll see
that is very simple to modify this routines to fit with your data.

Cheers

Hi Renato,

thanks for your hint. I will take a look at it. Maybe, your fortran routines
help to get into it faster; I actually just have hexa-elements.

Best Regards!
Fabian
