RES: [Paraview] clean to grid question...

Tue May 23 13:35:17 EDT 2006

I see, I tried what Brian suggested without success. Certainly the problem
is due to the Ensight reader in PV-4.2.3...I'll keep waiting the next PV
release anxiously  ;-)

thanks a lot 

Renato.

What Brian is suggesting is definitely the way to go. However, it may not
work. The EnSight reader produces the new multi-block format (hence all the
issues in 2.4) and D3 might not work well with it. This is something we will
address in the next release.

Ahh.. You have to invoke a filter that will request ghost cells (like
extract surface) before D3 will compute ghost cells. :)

Try adding an 'Extract Surface' filter after D3 and then show the surface in
wireframe. :)
