[vtkusers] Loading a multiple component structure in Paraview

[Paolo Bertolo]

Hello!

I would need your precious suggestions and help about something I'm  
trying to do with Paraview.
(Unfortunately, at the moment the Paraview guide book it's not  
available...)

My problem is as follows.

I have a FEM mesh file, whose cells are grouped together (to form a  
component) according to their properties.
These properties are not fixed, but they may change with respect to  
the time. And so does the geometry.

Up to now, I am able to convert all the data (both geometry and  
attributes) into VTK stand alone files (legacy or XML).
Usually I have many of those files, typically up to 30-40 files.

What I would like to do is, of course, load all of them at once. This  
could be easily done using XML file format, and this is what I am  
actually doing.
But it seems as the data is then considered as a whole, and not as  
being built up by many small stand alone entities. As a matter of  
fact, if I load every single file one by one in sequence, then I can  
set the properties (change the view to wire frame, or setting the  
transparency or hiding and so on) for each of them separately, but if  
I use an XML file I loose this possibility, which in fact is quite  
crucial to me (for post processing purposes, I need to hide some  
parts, or make them transparent).

Second point, I would like to _automatically_ load such a composite  
data-set, passing its file name(s?) as argument to the command line  
executable. Honestly, I still have to understand if you can pass more  
than one argument only to the --data= option, which, of course, would  
be an easy workaround to my problem.

Any suggestion is very welcome!

Thanks in advance,

Paolo Bertolo
