RES: RES: [Paraview] Saving IntegrateAttributes data

Tue Dec 19 07:09:26 EST 2006

Hi Jb

No, in fact my problem with Ensight's files are due to some specific filters
such as the "append datasets" and "clean to grid". Some time ago Berk
explained that the Ensight's readers were being redesigned and that there
would be some features not working properly until these implementation
issues completely solved. The last PV version, I'd say, with "maximum
support" to Ensight's file is the 2.2.1. The newer versions only have basic
support such as reading the files and ploting basic things.

Renato.

ps: If I'm saying something wrong regarding this subject (Ensight's files
and PV) or something has changed, please, update me.

What were the problems you had with ensight files? I had trouble because the
particles were stored using 1 offset, but the ensight reader creates them
using zero offset - this causes bad coordinates and dodgy output. I have a
fix for this that I still haven't checked in. If this is your problem,
please say and I'll check it in.
