[Paraview] Paraview Vtu to Exodus. Single block, multi element?

[Andi Hartarto]

Hi all, i need help please.

Introduction:
My problem is that I need to convert a vtu file into an exodus formatted
file that reads several element block data.
When I load my data in vtu, all i see is a white cubic block.
This block has 2 data arrays named tetrahedra rank and tetrahedra number.
When I change my coloring to tetrahedra rank, I can see 2 colors red and
blue coloring my block.

I want to save the vtu file into an exodus format file and load it to
another software but the other software only shows me the output of colors
if there are several element blocks.
 In my case, the vtu file converted to exodus has only 1 element block.
In paraview, I can go properties, add the variables of tetrahedra rank and
then change coloring then i see what i want to see.
But in the software I am supposed to load the data, I can't do that.
Im supposed to make my exodus data into 2 or more element blocks and then
load it in that software which makes the software goes "ok so there are
various data ! lets color it".

I don't know what should i do to change my vtu file with cell data of
tetrahedra rank clearly showing the 2 data sets into 2 element blocks.
I have tried to use edit> find data> extract selection > repeat for the
next > group the data.
I get a multi block data set. It didn't work. I need 1 block data set with
2 or more element data inside it.

Please help,
Andi

Re: [Paraview] [ParaView] data from multiple servers rendered in the same view

[claude]

Hello Sam,

thank you for the quick reply, I may not be doing it properly then. Each
time I toggle on the object to view, it ignores the current active
viewer and opens it in a new viewer/layout tab (or the viewer already
"linked" to the server if I didn't close that view yet). 

I attached 2 snapshots trying to show the behavior: each time I toggle
on one or the other data, it switches automatically the layout (here
"layout #2" and "layout #3"). Even if I close one of the layout and keep
only one, it will recreate a brand new one.

The servers are started with "$PARAVIEW/bin/pvserver --multi-clients"
and Paraview is started with "$PARAVIEW/bin/paraview --multi-servers".
Is this because the servers are both data+rendering and I should instead
have 2 data servers but one rendering server maybe?

Thanks again.

cheers

claude

Re: [Paraview] [ParaView] data from multiple servers rendered in the same view

[Samuel Key]

  
  
Claude,
I am quite certain that I am the least qualified individual
to answer your question, but I have been an avid PV user for
several years.
As you click on each view to make it the active view (blue
line around the view's perimeter), look at the pipeline browser.
You should see the on/off "eyeballs" change.
The appearance of the eyeball is either black for the datum
set in the current active view and the others are "grayed out,"
that is, inactive as in "not visible." You should be able to click
on a grayed out eyeball and make it active/visible in your
current selected view. 
  
Hope this helps.

Dear

  I am a new ParaView user and hopefully plugin developer, and

  There are several paraview servers setup and I am able to

  visualize the data
  on each server. However each data appear in a separate view
  and I would

  data are

  and server
  B are not held by the same people and do not share their data
  among
  themselves).
  Is there any way to "merge" the views together although they
  come from
  different sources? I couldn't find it in the UI but I wonder
  if this
  even possible/permitted by a software architecture standpoint.
  I would

  Thank you in advance.
  all the best
