Re: [Paraview] Error while trying to run Paraview on server

[Linh M. Nguyen]

Which OS and which version of the NVIDIA driver are you using?  Try running the 
command  'cat /proc/driver/nvidia/version’ to see which version you’re running. 
If on ubuntu 14.04 LTS make sure you have latest 331 (for bare metal) or 337 
beta if on EC2.  Nouveau and bumblebee drivers are historically problematic and 
it’s best to purge and blacklist them and install the drivers from NVIDIA when 
you see these types of errors.

Re: [Paraview] [EXTERNAL] Error while trying to run Paraview on server

[Rohit Narurkar]

No I am simply trying to run ParaView on a server computer, and I am
getting this error. I think OpenGL is missing, but could there be something
else?

Try running glxgears.  I wonder if you don’t have OpenGL installed.

Or, do you mean you are actually trying to run pvserver on a cluster?

[Paraview] Empty line printed from each core in coprocessorinitializewithpython() when doing in-situ

[Hong Yi]

In our in-situ run linking our simulation to ParaView Catalyst, I found an 
empty line was always printed from each core during Catalyst initialization (in 
coprocessorinitializewithpython() call). Although this is not a big deal, it 
becomes annoying when running on large number of cores. I traced the issue down 
some time ago and it appeared the empty line was printed from the statement 
"vtkPythonInterpreter::RunSimpleString(loadPythonModules.str().c_str());" in 
InitializePython() function in vtkCPPythonScriptPipeline.cxx. This empty line 
printout occurred in all ParaView versions we have tried including versions 
3.98, 4.0.1, and 4.1.0. I am wondering whether anybody else has experienced 
this minor but sometimes annoying issue, and whether I can get some

Re: [Paraview] Clarification on Paraview pvbatch run

Ok, so you are correctly using everything.
The question is now on the *OpenFOAMReader and if it properly use MPI to
read and distribute the data.*
*Which unfortunately I don't know.*

*If you want to force a redistribution of your data across your nodes, you
can use the D3 filter just after your reader.*

If it does not, then you right, everything will happen on the root node.

Hense a quick look at the script can help us determine which part need 
to change in order to truly use parallel processing.

The script is about creating slice and sweep animation. But it's
working fine, i think there is no problem in it.
Do you need the script to understand something about the
parallelization?

Let me know!

I think you are just missing that you should set WholeExtent in the

[Paraview] settings and default values

[Felipe Bordeu]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

hi to all,

I have a custom filter with default values (defined in the xml). but now
I want to populate the default values from the data coming from the
plugin settings.

so a have a  with the descriptions of my
settings window. but I don't know how to put this information into my
filter.

I'm trying something like this

vtkSMIntVectorProperty::SafeDownCast(proxy()->GetProperty("GUIMaxNbModes"))->SetElement(0,settings->value("PxdmfSettings.GUIMaxNbModes",100).toInt());

(in the constructor of a pqPropertyWidget) but I don't know if this is
the right way.

Also when I use the setting menu, my data ("GUIMaxNbModes") is written
in the ParaView4.1.0.ini AND in the UserSettings.json. Why ???

Thank to all
Felipe

Re: [Paraview] Clarification on Paraview pvbatch run

[Daniele Obiso]

Hi Sebastien,

thanks for the reply!

The script is about creating slice and sweep animation. But it's working 
fine, i think there is no problem in it.

Do you need the script to understand something about the parallelization?

Let me know!

Re: [Paraview] [EXTERNAL] Memory explosion and strange behavior -- Linux -- 'clip' -- 360 MB file needs 60 GB ??

[Robert.Atwood]

Im sure that should be possible somehow, maybe not the specific data I 
mentioned which is an external user's unpublished work so far, but we can just 
get some more if there's some useful collaboration to be had. 

I've been 'playing' with Paraview since the CCPi and Harwell Imaging 
Partnership meeting showed the latest release and also because the latest 
de-bugging of our central file system is arguing against allowing the 
'visualization workstation' being directly connected to the central storage for 
technical reasons, thus the client/server model becomes very attractive, 
allowing the machine that actually reads data to be inside the computer cluster 
rack, while another machine displays the result , I think this require our 
cluster admins to do something-or-other , so I need to have some good argument 
that it will indeed do what we want (which also means figuring out what we 
actually want) to get that task added to their already-lengthy list. 

In the first instance, we want external facility users to at least be able to 
do SOMETHING with their data while still at their experiment. So it takes about 
1/2 hour to collect the raw data, another 40 min to reconstruct the 160 GB 3-d 
image , then what???

[Paraview] Make animation from steady state result

[minh hien]

Hi all,

I got steady state solution for my problem. After plotting streamlines at
steady state, I would like to make animation showing moving of spheres
(resulted from Glyph filter) on the streamlines, the spheres' velocity
should be defined by the flow velocity. How can I make this?
Any suggestion would be very much appreciated.

Thank you in advance.

Re: [Paraview] exporting selection labels to an SVG as editable/movable text-objects

[David Lonie]

Hi Roman,

Aha, the cube axis actors are still using vtkVectorText to render the text.
vtkVectorText is a text source that produces polydata to forms the
characters of the text string, and the actual text information is lost by
the time the SVG exporter processes the actors.

There was an effort in VTK to convert the cube axes to use vtkTextActor3D,
which would allow proper text exporting, but this is disabled in ParaView,
and I believe it is only experimental at this point. So unfortunately, this
is the best it gets for that particular text source at the moment.

Sorry for the misinformation earlier -- I thought you were referring to a
ParaView text source, which should export as editable text.

Dave

[Paraview] Crash of pvserver using pqActiveObjects::instance()

[Christian Andreas]

Hello,
I'm using an in-house written Plugin to read time dependent simulation 
data. The plugin has an option to reposition the camera
during the RequestData routine in order to keep the focus on the centre 
of a moving structure of interest.

For that purpose we use the pqActiveObjects::instance()  singleton.

As long as the plugin is used to read the data without involving a 
pvserver (using Paraview only),
everything works as expected. But if the data is processed with a 
pvserver, a call of


pqActiveObjects* tempInstance = &( pqActiveObjects::instance() );

results in a crash of the server. We use Paraview 4.0.1 64bit on ubuntu 
12.04 systems. And paraview is configured to render remotely with a

"Remote Render Threshold" of 0MBytes.
Is this kind of repositioning illegal and works just accidentally in the 
case of local execution or is there a way to solve this problem?


Best regards
Christian

[Paraview] Clarification on Paraview pvbatch run

[Daniele Obiso]

Hi All,

i'm writing here because i would understand better the functionality of 
pvbatch in Paraview.


At moment i'm able to run Paraview in batch launching a python script, 
and it works good.


Here the line command i launch:
_//software/Paraview/ParaView-3.12.0-Linux-x86_64/lib/paraview-3.12/mpirun 
-np 6 /software/Paraview/ParaView-3.12.0-Linux-x86_64/bin/pvbatch 
python_script.py /_


The problem is that monitoring at processors loads and memory 
consumption, it seems that it's actually working on one single 
processor; in fact if i switch to /-np 2/ or even /-np1/ nothing changes 
in terms of computing time.
This is happening with various Paraview versions (3.10 -3.12-4.1); is 
there something missing in the line command? Some other options? Are 
some Paraview filters just working as serial?





Another question would be about running pvbatch on clusters without 
graphic cards: i know it's possible, compiling Paraview with OSMesa, and 
adding in the command line  the option

--/use-offscreen-rendering/. Could someone clarify also this point?

Thank you all in advance!
Daniele
