Question about probe point data

Hello,
I am trying to probe point based data with Paraview.
What I did is:
1) Create probe points with "ProbeLocations"
2) Then use "Resample With Dataset", choose input as the data that I have already had and source as "ProbeLocations" that I created in the previous step.

The trouble that i have is:  All field data including coordinates are all zero.

Could someone help me out?

Thank you very much!

pv5.0 multi-page tiff in parallel

Hi,

I’ve been looking at loading tiffs as volumes using pv5.0 and am running into trouble doing this in parallel. 

Loading a stack of tiff files as a volume works great, both serially and in parallel.  And I can load a multi-page tiff as a volume using a single pvserver just fine.  But when I run the pvserver in parallel and try to load a multi-page tiff pv crashes while trying to load.  No error messages are given (beyond the usual mpi errors about one of the processes terminating badly).

I’m wondering if anyone else has had success trying to do this?

Thanks
joe

EGL build of ParaView

Hello,

I am trying to make the EGL build of ParaView work, but I am encountering some issues.

First, here is the configure line I used to build ParaView:
cmake .. \ -DBUILD_TESTING=OFF -DPARAVIEW_ENABLE_CATALYST=ON -DPARAVIEW_ENABLE_PYTHON=ON \ -DPARAVIEW_INSTALL_DEVELOPMENT_FILES=ON -DPARAVIEW_USE_MPI=ON \ -DVTK_RENDERING_BACKEND=OpenGL2 -DVTK_USE_OFFSCREEN_EGL=ON \ -DVTK_USE_X=OFF -DPARAVIEW_BUILD_QT_GUI=OFF \ -DEGL_gldispatch_LIBRARY=<path_to_libGLdispatch.so.0> \ -DEGL_INCLUDE_DIR=<path_to_EGL_includes> \ -DCMAKE_INSTALL_PREFIX=<install_prefix>

Everything then builds and installs correctly.

But when I start a pvserver (with no X server launched) on the server where the data is stored and with a graphic card. I end up having the following issue in a ParaView pop-up:

"

OpenGL drivers on the server side don't support

required OpenGL features for basic rendering.

Remote rendering will be disabled.


OpenGL Vendor: NVIDIA Corporation

OpenGL Version: 4.5.0 NVIDIA 358.16

OpenGL Renderer: Tesla K80/PCIe/SSE2

"

And then I tried to use volume rendering, but I end up with this error:
"
Some of the representations in this view require remote rendering which, however, is not available. Rendering may not work as expected.
"
And VR does not work.

I managed to replicate this issue, with both a Nvidia Tesla K80 and GTX 470 with the 358.16 driver from NVidia on a Ubuntu 14.04.

However, when I add the "--disable-xdisplay-test" option to the pvserver. I don't get the error regarding to OpenGL drivers and I am able to do remote rendering on the server side.

I also tried adding the "–egl-device-index=0" instead of "--disable-xdisplay-test", but I am getting the OpenGL error.

Is there something I missed in my ParaView build ?
I guess I should be able to run the pvserver without the "--disable-xdisplay-test" option, isn't it ?

Another last question, is the EGL internal rendering resolution available for modification or will it fit the current view of ParaView ? (e.g. for doing screenshots)


Thanks in advance for the answers,

Best regards,
Alexandre Ancel

Migrating from ParaView 4.0.1 to 5.0.0

I just upgraded from ver. 4.0.1 to 5.0.0. I am reading the same data set, a frame sequence of AVS_UCD files and  I am trying to play a movie.

The playing speed in 5.0.0 is much slower than in 4.0.1, at least two times slower. I am not using MPI option in either case. What settings should I look for to speed up the 5.0.0 performance?

Thanks,

Vlad

Adding time steps to a data set

Hello

I have several exodus files which are snapshots of an optimization history. Each snapshot reflects a design change and how it is gradually being improved and more optimal. I want to make a movie showing this optimization history.

What I have done so far is to add all the files in the pipeline showing the design field, add each file to the Animation View as a frame and play with the Opacity and the time intervals to show the design transitions. This looks alright, but I what I think that would look better is to use a Temporal Interpolator filter. For that I would need to have a time series. I tried modifying the file names and adjust them to the convention filename.e-s.001, filename.e-s.002, etc, but this doesn’t do anything. I think the reason is because the exodus files do not contain anything related to time. Is this correct? How could I add time to my exodus files within paraview?

Thanks
Miguel

Plot on sorted lines with Cell Array

Dear Paraview users,

I want to plot a field on cells with the same discretization as my
mesh. So I don't use Plot over line, but Plot on sorted lines with 2
slices to get the polyline to plot data on.

It works well with a field on nodes, but I can't get a result with a
field on cell. Of course if I use Cell data point data, I get a plot,
but with mean values on the nodes.

In Plot on sorted lines properties, if I choose Attribute type Cell
data, I can't see my field on cells in the list of available fields.

To reproduce the issue:
- download the dataset (802K) : http://bourcier.eu/secteur.tgz
- open it
- display the field U2
- apply a slice in Z normal
- apply a slice in Y normal
- apply Plot on sorted lines
- change Attribute type to Cell data: the field U2 is not available.
- apply the filter Cell data to point data (with Pass Cell Data
ticked) before Plot on sorted lines
- in Point Data, U2 is available, but the resulting plot has mean
values on nodes between cells that have not the same value on the left
and on the right. Zoom at the right end of the line to see it.
- in Cell Data, U2 is now also available, but nothing is displayed. I
would have expected to see a stairstep graph.

Have you an idea on how to get this?

Thank you.

Cut plane average velocity over time

Dear all,

 

I am working with 3D velocity fields over time. I would like to extract average velocity values at given cut planes. Preferably, I would like to be able to plot the average velocity of this plane over time.

 

For a single point on the plane I can choose “Select Points On” and then “PlotSelectionOverTime”, but I would like to get an average over an entire cut plane (over time).

 

Does anyone know how to do that?

 

Thanks for the help,

 

/David

How to uncheck Map Scalars using ParaView Python console

Hi,

I am trying to set RGB color based on a data with 3 components. Unchecking "Map Scalars" checkbox under
Scalar coloring does the trick in GUI mode. Is there a way to do it using pvpython (scripts) ?

How do I set up the lookup table to do the same thing ?

Thanks,
Tias

Periodicity aware streamline?

Hi,

I have a simulation that is periodic in 2 of the 3 directions and I would like to plot some streamlines coming
from specific points in the domain. Some of these points are close to one of the periodic edges. 

Is there a way to tell Paraview that the domain is periodic and that streamline integration can continue
from the opposite face? 

Thanks,

How to give Python access to a Plugin

Hello,

I don't seem to be able to access properties in the VRPlugin from a Python source or filter. I can see other
Plugins in the Python Shell (if I load the plugin before opening the shell for the first time), but only
filter or source plugins. Is this related to the .xml file in some plugin source directories?

I ultimately want to allow a VR CAVE user to select points in 3D space with a tracked device, much like the
"Interactive Select Points On" feature in the GUI in 4.4.0 and later. If anybody has suggestions for how to
do this, I would be appreciative.

Combining files in an animation

Hello

Newbie here, hopefully my question is not too obvious. I have two .e files from two consecutive optimization iterations. I want to show how the results evolve from one iteration to the next with an animation. What I did was to add the two files in the animation and modify the field Opacity from 1 to 0 for the first iteration and from 0 to 1 for the second one during the same time span from 0 to 1. Both with a Ramp interpolation. I would like to see that transition combined. Instead of having a value of 0.5 for both files at time 0.5, I would like to have an overall result of 1. Is it possible to add the Opacities and have that represented in the Animation?

Thanks
Miguel
