Re: [Paraview] animation: files, pgmable source

[Utkarsh Ayachit]

Randy,

You attempting to mix the Python scripting for data processing and
Python scripting for batch scripting. The two environments are
separate. Here's how I'd tackle it.

1. Make your "Programmable Source" become a temporal source i.e.
report to ParaView that it can produce timesteps matching the files
your file series. See [i]. If you get this right, you shuold be able
to render through all the files by hitting "Play" in the VCR control
in the UI.
2. Now you can write a batch script that either loads the predefined
pvsm state file or builds up the pipeline in Python itself and the
either uses `SaveScreenshot` or `SaveAnimation` to save out the
animation.

You can then mix in camera animations too. You can always use the
Python tracing in UI to figure out how to save images and/or animation
in the batch scripting environment.

Hope that helps.
Utkarsh

Re: [Paraview] loading multiple state-files without hiding and resetting already loaded objects

[Cory Quammen]

Hi Roman,

Sorry I failed to follow up. Did you find a solution to this problem?

This line in your script looks funny to me:

d[props] = pvs.GetProperty(repr, props[0])

Shouldn't props[0] just be props?

Thanks,
Cory

Re: [Paraview] How to read the file info in *pvd file

[Cory Quammen]

Did you make progress on this? You should just be able to use your
favorite Python XML module to locate all the  elements and
find the "file" attributes to get the *pvtu file names. Then you can
parse those *pvtu XML files to get whatever information you want. One
such module is documented here:
https://docs.python.org/2/library/xml.etree.elementtree.html.

[Paraview] Memory issue for remote visualization

[Dennis Conklin]

All,

As we start down the road to parallel visualization, our first baby steps are 
to try remote visualization.

In Redhat, I ssh onto a node with ~30 gigs of memory available (free -m)   I 
start pvserver.
Back on my machine I launch paraview541 and connect to the server.  The Memory 
Inspector shows 2.1 GB of total system ram on the server.
If I try to load a model of any size, the server bombs on a segmentation error 
(memory).

If I log onto the remote node with 30 GB free memory, I can only run standalone 
paraview if I use the -mesa-llvm command line.   When I do this,  Memory 
Inspector in standalone Paraview says there is only 2.1 GB of total system 
memory.

Am I missing something - I don't see  how this is ever going to work if neither 
a remote paraview or a remote pvserver can see and/or access the available free 
memory on the remote machine.

Thanks for any hints

Dennis

[Paraview] Windows Mixed Reality

[Ken Martin]

Just a FYI, I just had a chance to test out a new Windows Mixed Reality
headset and it seems to work well with VTK and ParaView through the SteamVR
driver. I was testing the new Dell Visor headset and controller. The
controllers show up properly and the controls map to reasonable settings.
Tracking was surprisingly good.

[Paraview] animation: files, pgmable source

[Heiland, Randy]

I’m probably missing a basic concept and hoping someone can enlighten me. I 
have a pipeline with a Programmable Source that reads in a (non-VTK formatted) 
file, I process it and then I have filters in my pipeline that act on that 
data. I want to be able to feed multiple files to the pipeline, save images 
and/or create animations. I naively created a Python function in the Pgmable 
Source, then save the PV State to a Python script, thinking I could call the 
function from the end of that script. Doesn’t seem to be possible. And I 
confess I’ve not given this deep thought - it’s easier to ask the experts :-)  
Bottom line, we want to make this as dead simple for our own users.

Fwiw, I’ve zipped up 2 files - a .pvsm and a sample data file here: 
http://pages.iu.edu/~heiland/physicell/pv_pcell.zip . You’d need to edit the 
“dir” path in the Pgmable Source.

Initially, I just want to save images/animation (over multiple files) with a 
fixed camera view; later, it’d be nice to have simultaneous camera movement.

thanks, Randy

Re: [Paraview] wallShearStress Calculation in Paraview

[Andy Bauer]

There's no general way to compute gradients normal to the surface so you
need to compute the gradient on the simulation's cells (e.g. volumetric
cells for 3D). You can use the Gradient Of Unstructured Data set to do
that. Then extract the surface as Mathi said, use the Normals filter to
compute the normals, use the Calculator filter to multiply the normals by
the gradient and the viscosity and you'll have the wall shear stress over
the entire boundary surface. You can then select the cells you want to show
the WSS over the exact portion of the desired boundary.

What do you mean? Do you mean update a Programmable Source once every
time period?

Re: [Paraview] wallShearStress Calculation in Paraview

[Ezhilmathi Krishnasamy]

Hi Ahmet,

What you can do that is, use the filter name called extract surface.
once you get that surface either you can export those values in form of
from elements or from the points.

It might work, or you may get more clear explanation from this forum.

Cheers,
Mathi

[Paraview] wallShearStress Calculation in Paraview

[Ahmet Ahmet]

Hello everyone,

I have results with OpenFOAM including p,T,U outputs. Due to some reasons,
I can't use wallShearStress or wallgradU utility in OF. So, I have to
calculate it on Paraview. I saw many topics related to that on google, but
I could not find a satisfactory answer. My case is 3-D, compressible and
laminar but we can think about incompressible and may be 2-D.

I think the most important part for WSS is to calculate velocity gradient.
My unsolved problem is to calculate that. How can I calculate gradients on
the wall? I have no-slip wall, that is u=0 and with *Gradient of
Unstructured DataSet/Compute Derivatives *filters, I obtained 0 on the
wall. I think the values in the nearest mesh to the wall should be
accounted for. To do that, what should I do?

*Note:*

   1. The walls are not aligned with a coordinate axis. For this part, I
   tried to extract the wall surface and generate normal vectors.
   2. As an alternative to get directly on wall, I tried to get slice a
   little bit over the wall surface and then take surface vector on slice then
   gradient of unstructured dataset on surface vector. That gives me a result
   but I am not sure it's true.


This may be simple for you, sorry for that.
Thank you in advance,
Ahmet

Hi all!

I have a structure from points and lines. The POINT_DATA contains some 
displacement vectors. When I load it in Paraview and use Warp by Vector, it 
does not give me any displacement or change in color.

Is my code wrong?

Please see my file attached.


Also, I would like to add under POINT_DATA more vector fields (example, VECTORS 
mode1 float, VECTORS mode2 float and so on..but it reads only the first field 
of vectors, how can I solve that?)


Thank you all in advance!

Thanks, good to know. We'll try 5.2 (qt4) if the issue surfaces again,

Hi,

In our paraview course two weeks ago we had a student that had trouble
running Paraview 5.4.1 (official windows 64-bit binaries) under windows
10. The symptoms were that the main menu bar was invisible and that the
mouse cursor did not match up with the position of the click event,
making it very hard to do anything. It seemed the menu bar somehow had
shifted under the window title bar, causing the misalignment.

As this laptop was an optimus system we figured it might have something
to do with that. After some fiddling we found that right-clicking on
paraview.exe and picking Run with graphics processor ->
High-performance
NVIDIA processor solved the problem.

Is this a known issue?

Regards,
Paul

Hi,

Is there a possibility to perform a cyclic update of a Programmable Source?
