[Paraview] ParaView session state

[eduardo]

Hello list,

Where is the data structure(s) in the code where all the objects for the state 
of a particular ParaView session are kept while it is running?. I have been 
reading the code but can't figure it out. As far as I understand, the state 
(which can be saved to XML) is all it takes to recreate a session (Am I right 
here? Probably you need the input data as well, right?).

Thanks for the help!,
Eduardo.

How to you run ArcticViewer? Which OS are you on?

 Hi Chris,

 Thanks for your interest. The following Python scripts provide an
 example on how to generate such dataset.

 https://github.com/Kitware/arctic-viewer/blob/master/scripts
 /examples/paraview/mpas/raw-probe-flat-earth.py
 https://github.com/Kitware/arctic-viewer/blob/master/scripts
 /examples/vtk/mpas/raw-probe-flat-earth.py

 Moreover, depending on your data structure, the way you want to iterate
 through time may differ.
 The example below show the can dataset with a geometry export. But at
 least, it also show how to control time in ParaView when the reader is Time
 aware.

 https://github.com/Kitware/arctic-viewer/blob/master/scripts
 /examples/paraview/samples/VTKGeometry-can.py

 Let me know if you need additional information regarding that script
 and what it is doing.

 Seb

Re: [Paraview] Convert VTU for Arctic Viewer

[Chris Marsh]

Ah yes, that works. Thanks.

I have modified the 2nd example (vtk) to work on a single vtu file I have
(so no time) and output a single array. It appears to complete fully and it
writes the the tar fiels to my data directory.
When I try to serve up these data, I'm presented with a static image of the
head sample dataset I had previously loaded. Rebooting and killall node did
not resolve this.
Using a different port shows a blank page.

Thanks for the help,

Cheers
Chris

Just download ParaView binary and use pvpython. You will have everything
required meaning both vtk and paraview side of things.

Hi Sebastien,
This is very helpful, thanks!

Current hangup is that vtk.web.* is not available. I've installed vtk
--with-python via homebrew (I use vtk successfully from python regularly).
However the web components do not seem available. Googling isn't helping
me. Any suggestions?

Cheers

Re: [Paraview] Apply Tecplot table format file (.dat)

[Deij-van Rijswijk, Menno]

Hi all,


I created the Tecplot table data importer a while ago. As the tecplot file 
format is very flexible, it is impossible to create a reader that caters to all 
possibilities (without knowledge on how the format can be used). So, the 
residuals.dat file is an example that our simulation code writes and that is 
readable by Tecplot (and now also ParaView). Its reader is based on the CSV 
reader that existed already. Currently, the VARIABLES must be on one line and 
the data needs to be in the same number of columns and the VARIABLES. 
Otherwise, as you experienced, it won't work.


You're more than welcome to expand the support for more ways in which the 
format can be used. Just be sure that the residuals.dat file can still be read 
;-)


All the best,
Menno

Hello

Please keep the discussion in the mailing list so everyone can contribute.

Your dataset (OJF_Out-SPECIES.DAT) does not seem to have the right Tecplot 
format.
Please take a look to this tecplot .dat file (residuals.dat) , wich can be 
opened with ParaView flawlessly.
You may try to correct your file manually or correct the way it was generated.

Re: [Paraview] Convert VTU for Arctic Viewer

Hi Chris,

Thanks for your interest. The following Python scripts provide an example
on how to generate such dataset.

https://github.com/Kitware/arctic-viewer/blob/master/scripts/examples/paraview/mpas/raw-probe-flat-earth.py
https://github.com/Kitware/arctic-viewer/blob/master/scripts/examples/vtk/mpas/raw-probe-flat-earth.py

Moreover, depending on your data structure, the way you want to iterate
through time may differ.
The example below show the can dataset with a geometry export. But at
least, it also show how to control time in ParaView when the reader is Time
aware.

Let me know if you need additional information regarding that script and
what it is doing.

Hello Robert,

thank you for your reply and we are looking forward to your email. Joe has 
made some progress on that front on one of our newly installed system. We are 
seeing some 12x performance gain on our compute nodes with GPU hardware. We 
are looking into system wide deployment and having to be able to do it from 
superbuild will significantly help simplify our deployment process.

Hi Simon,

Currently the VTK-m support that is offered by the ParaView superbuild doesn't 
support enabling CUDA. I am in the process of adding this option to the 
superbuild and can notify you when this feature has been merged in. In the 
short-term you would want to manual modify the vtk-m CMAKE_ARGS entry in the 
superbuild to have VTKm_ENABLE_CUDA:BOOL=ON.

Re: [Paraview] parallel processing in volume rendering and Merge Blocks filter ...

[Andy Bauer]

Hi Ufuk,

The Merge Blocks filter will work locally on each process and shouldn't
move any of the data between MPI processes since it's a trivially parallel
operation. When doing volume rendering of unstructured grids (the output
dataset type of the merge blocks filter) with Ice-T in parallel, there will
be data moved around in order to simplify and reduce the parallel
communication by constructing convex partitions.

I don't know how NVIDIA's Index plugin works in parallel but my guess would
be that it also wants convex partitions.

Cheers,
Andy

Re: [Paraview] Apply Tecplot table format file (.dat)

[Mathieu Westphal]

Hello

Please keep the discussion in the mailing list so everyone can contribute.

Your dataset (OJF_Out-SPECIES.DAT) does not seem to have the right Tecplot
format.
Please take a look to this tecplot .dat file (residuals.dat) , wich can be
opened with ParaView flawlessly.
You may try to correct your file manually or correct the way it was
generated.

Best,

Mathieu Westphal

Hello

Can you please share the error ?
Can you share your dataset ?

Re: [Paraview] parallel processing in volume rendering and Merge Blocks filter ...

[Ufuk Utku Turuncoglu (BE)]

Hi Andy,

Thanks for the clarification. One minor question, after applying Merge 
Blocks is it still processing in serial mode or can i use MPI to improve 
the performance? By the way, i am also using NVIDIA Index plugin. I 
think that it supports parallel rendering but again not for multi block 
dataset. Right?


Regards,

--ufuk

Hi Ufuk,

ParaView doesn't currently support volume rendering of multiblock 
datasets, even in serial, so using the Merge Blocks filter is probably 
the best way to do any volume rendering of your dataset.


Cheers,
Andy
