RES: [Paraview] Saving IntegrateAttributes data

[rnelias]

Hi Theophane,

Thanks for your hint. I tried to do what you said but the "integrate
attributes" does not have the XY Plot, at least in ParaView 2.2.1 which is
the version that I'm still using. I'm forced to keep using this version
because, for me, this is the best version for whom works with Ensight files.
BTW, I've just checked the PV 2.4.4 version and the "integrate attributes"
filter in this version actually has the XY-Plot. Unfortunately, I can't use
this version because the "append datasets" and "clean to grid" filters don't
work with my Ensight files (I have to load several pieces of model and
"glue" these parts because my ran was done in parallel). 

I know that most of these annoyances are due to the limitations of PV with
Ensight's format but I'd really like to keep using Ensight's format. The VTK
formats are a bit strange to program and use in Fortran (I even can't
understand the VTK format structure). It would be good to have a tool to
translate these datasets between some formats or some import/export
capability in PV. I started to do a VTK/TCL script to translate files
between Ensight and VTK format but I gave up after discovered that VTK
formats do not have an easy way to implement transient data sets as
Ensight's format has.

Anyway, thank's for your help. I'll keep struggling with my Ensight's files
;o)

Hi Renato,

I have used the Integrate Attributes filter with transient datasets and I
did the following to save the integrated values across timesteps.
- load the transient data
- integrate the value you need for the first time step (I think you need to
enable Show XYPlot in the Integrate Attributes filter)
- click Play animation button (watch the XYplot update!)
- click SaveAsCVS button in the Integrate Attributes filter at the end of
the animation

This should give the list of the integrated values for all the timesteps.
For information, I modified the filter and related classes to save transient
data in .dat format which I found more convenient for my usage rather than
.cvs.

Cheers,
Theophane
