Fabian,

The only way to this currently, is to use some of the XML processing
libraries  (either from ParaView) or modules provided by Python
(https://docs.python.org/2/library/xml.html) to process the XML to
change the filename in the state file before loading it.

[Paraview] Ensight Files - crash with 3.10 and 3.12

[Fabian Braennstroem]

Hello,

I have a problem with Ensight files created by OpenFOAM.
Paraview crashs as soon as I try to create a slice directly after 
loading the file... but only for version 3.10 and 3.12, but it

works for 3.8.

fbraenns@elephant: 
/data2/WORK/fbraenns/R2N/CFD/Saloon/VI2N_VI1N/M02_B03_G07_OF__Mesh_82Mio_Case1 
$ pv12
Find an unexpected case. The input polyhedron cell may not be a water 
tight or the polygonal faces may not be planar. Contouring will 
continue, but this cell may not be processed correctly.

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

I am not sure, what you mean with lines in my input, but yes I did cut

though as Paul mentioned, this error was there earlier as well. I check 
again.

It would be great to fix this in the 3.12.

The ParaView team is pleased to announce the availability of the
ParaView 3.12.0 Release Candidate 2 binaries for download on the
ParaView (http://paraview.org/paraview/resources/software.html).
ParaView 3.12 can be considered as a bug-fix release with over
180 issues resolved. The detailed list can be found at
http://www.paraview.org/Bug/changelog_page.php.

With Python being one of the preferred means of interacting with
ParaView, we've added support to create animation tracks that use
Python scripts to build highly customized animations.

Plugins support is one of the strong points of ParaView and with
this release, we've made it easier to load deployed plugins on the
server processes as well. All distributed plugins are now listed
on the client as well as the server side.

The release includes updates to LANL's streaming framework.
The multiresolution streaming view now automatically adjusts
resolution to match the projected image size. Also, VTK filters
are now able to modify meta-information which means they can
modify the data while still allowing the streaming framework to
cull and prioritize pieces. An example is a new spherical warp
filter that projects flat data onto the globe while correctly
tracking piece bounding boxes.

Also, there are updates to support users of the cosmology
and windblade formats. For example the MaskPoints filter (used to
place glyphs and in other places) was updated with new options
that improve random sampling in parallel. Likewise VTK's Gaussian
Splatter filter is now exposed in ParaView which makes it easy to
visualize point set data with imaging filters. The cosmo and
windblade readers have also been revised.

This version includes some major changes under the
covers. ParaView 3.12 includes improvements to the underpinnings
of ParaView ServerManager. The communication layer under the
ParaView ServerManager was upgraded to minimize communication as
well as making it easier to debug and trace messages being
exchanged between client and server. We now use Google Protocol
Buffers, for example, to exchange messages between client and server.

In addition, there are several small but notable improvements
included in this release for example, the views now use caching to
avoid re-renders from repaints due to menus and dialogs popup up
on the screen; volume rendering of uniform grids now supports
shading; ability to enable specular highlights when using scalar
coloring and others.

The updated userguide can be accessed at:
http://www.paraview.org/Wiki/ParaView/Users_Guide/Table_Of_Contents
Or in PDF form at:
http://paraview.org/files/v3.12/ParaView%20Users%20Guide%20v3.12.pdf

The development team has adopted a git-workflow-based development
process that is integrated with the ParaView Bug Tracker
(http://paraview.org/Bug). The workflow enables us to track every
change that goes into ParaView and maintain a stable repository.

We value your feedback. Please use

think" link on paraview.org  to leave your
feedback and vote for new features.

In the worst case, you simply want to install python 2.7 (same as

I check if the numpy import works well with the binary package on a

For now, I'm on a windows machine.

http://markmail.org/message/sq7dafegnrh7exth
This was obviously a similar problem, but now it is not the trace, but 
the state file in 3.10.1.




Could you let me know, for each .foam file, what data types the
multiblock dataset contains?  Are the blocks unstructured grid,
polydata, other?  You should be able to avoid the problem by commenting
line 186 in your plot.py file, where ScalarOpacityUnitDistance is assigned.


Both .foam files are bascically the same geometry calculated with just a 
different equation solver... so the structure should be quite similar.

Just commenting outhe the line 186 gives same error for other variables:

[ceplx049] 01__56T_SST_1.7 > pvpython plot.py

Hi,

I am frequently using the openfoam reader for a decomposed case.
Is there a way to set the time before one needs to load the first "zero"
time step? Using a reconstructed case type, it is possible to set the wanted
time step.

Thanks in advance!

See http://paraview.org/Wiki/Plugin_HowTo#Adding_Categories_to_the_Filters_Menu

Thanks! Maybe, a simple mechanism to group macros is by defining the

And with

it is quite easy to write to some file based the input...

[Paraview] Python Macro group macros, scripts with user input, arrangement of filters and bug in trace

[Fabian Braennstroem]

Hello,

I am using quite a few python macros for my daily work. Mostly this 
works quite nice! Unfortunately I do not find a way, how to arrange some 
to certain groups. E.g. I would like to group macros for setting certain 
views and other to a group, where special filters are adjusted. Is it 
somehow possible to get a sub-menu entry for the groups?


For some macros it would be great, if I can give further user input. I 
there a best way how to do it? Maybe, it is even possible that small 
window with a list of options opens up!?


In addition to this I would like to create sub-menus for own filters. Is 
there a way to do this? Probably I could create a python macro for this, 
but then the list of macros would rise... and it will be even more 
difficult to get an overview.


At the end, I would like to mention, that in 3.10.0 using the python 
trace, there was no recording of the camera zoom (I think it was missing 
for saving certain camera settings from the main windows as well)... I 
will now check it for 3.10.1.


Would be great, if you have some hints!
Thanks advance!

Hi,

I would like to mention, that the above version crashs for OpenFOAM 
data, when using surface vector filters on a slice while tracing.

Re: [Paraview] Multiblock Dataset: Extract Block in Python

Hi,

I wonder, if this works now in the current 3.10 release!?

Thanks Utkarsh, Berk:

I found a similar posting:

http://www.mail-archive.com/paraview@paraview.org/msg02936.html. Is
there o bug for it so far?

My current workaround is to extract BLocks (from EnsightReader) and
numbering them using Python functinality:

dict ={}
source = GetActiveSource()
if not source:
 raise RuntimeError, "This macro needs an active pipeline object"
source.UpdatePipeline()
cdi = source.GetDataInformation().GetCompositeDataInformation()
blocks = cdi.GetNumberOfChildren()
for i in range(blocks):
 dict.update(cdi.GetDataInformation(i) : i+1)


Afterwards dictionary dict contains name of the block and its according
index. However it only works if:

* Blocks are numbered starting from one without spaces

This was the case for all my tests so far. Is this always right?

Regards.

Dear all,

I want to extract certain zones (using name filtering) from an Ensight

Currently I have the names of the zones to extract in a Python list. I do not 
know how to proceed. I guess I need to get the IDs of these zones? How to do 
that? How to extract the zones?
I am working with Paraview 3.6.2 and the Trace did not help me much for this. 
Where do I get some more documentation than in the wiki? Thanks.

Yes, I attached the error messages (using pvpython and running the 
script from the gui) and scripts; the original state file pvsm works 
fine. The script 'test.py' (with two different error messages 
testError*) is the one, which was saved as a state file and 
'pyCalculator.py' (errormsg.txt) the one which was created using 'Start 
trace' and 'stop trace'...

Hi Fabian,

Please remember to include the paraview mailing list when you reply.

What you report is a bug, but you can avoid it- when you open your
openfoam dataset you should check each block that you want to load
*before you hit apply for the first time*

The problem is the first time you load your data and click apply,
paraview sees a multiblock dataset containing only unstructured grid
data, so it creates an unstructured grid display.  This display has
properties related to volume rendering, and these properties are
recorded in the trace script.  Later you must have enabled more blocks,
so that multiblock dataset now contains unstructured grid and polydata.
When the trace script is replayed, paraview sees the unstructured grid
and polydata datasets, so it creates a geometry display instead of an
unstructured grid display.  The geometry display lacks the volume
rendering properties.

Moving the lines up so they appear after the constructors of Slice1,

You are using 3.8.0, not 3.8.1.  If you use 3.8.1 to generate the trace

Your script can also be fixed by hand-  editing test_trace.py and move
the lines at the very bottom modifying Slice1, Slice2 and Slice3.
Moving the lines up so they appear after the constructors of Slice1,
Slice2, and Slice3.

Hi Fabian,

Regarding your issue of python trace state not replicating your
paraview
state exactly, I believe both issues you quote (camera position
and cut
filter's slice property) have been addressed in the latest
version of
paraview.  If not, can you list the steps required to repeat the
problem?  I can't find bug reports for these issues, but below I
have
copied the git logs for the commits the addressed the issues.

commit f3f73df79fe4ca377297885c4c71bcba661b165d

 BUG: Add method to disable the first render ResetCamera.

 Added python method
paraview.simple._DisableFirstRenderResetCamera()
 and included it at the top of all generated trace scripts.
  This is
 tested by PythonSMTraceTest1 since I removed the extra
'Render()'
 call from the test which was there to work around the issue.

 BUG: Group helper proxies with the proxy using the helper.

 For example, now 'my_slice.SliceType.Normal' is mapped to
my_slice
 instead of the SliceType helper proxy.  Now when you trace
state,
 the helper proxy's properties are grouped with the parent
proxy.
 Previously all helper proxy properties were listed at the very
     end of the trace, and that was incorrect.

Re: [Paraview] pvbatch: Manipulate file list of loaded state file

Hello Karl,

oh, I hoped you could get it to work...
Is the new option, you are mentioning, available in the latest git 
version? With 3.8.0 I am not able to see it. And it would be great to 
access this by python!?

Hello Fabian,

I never got that working and eventually gave up.
But - this was a year ago. In the meantime Utkarsh and David have added a 
possibility to alter the file when loading a state file. In the GUI a dialog 
pops up when loading a state file which allows to change every file referenced 
in the state file. I haven't tried, though, whether this feature is available 
from Python.

Hello Karl,

I wonder, if you had success with your approach!? Actually, I would like
to do similar with these lines:

from paraview.simple import *
servermanager.LoadState("/home/gcae504/Dissertation/3D_Nielsen/OpenFoam/01_SAS_SSTF_URANS/01__56T_SST/STREAM_SLICE0.pvsm")
SetActiveView(GetRenderView())
Render()
sources=GetSources()
print "Sources: ", sources
FindSource("Slice1").SliceType.Origin = [5.0, 1.0, 1.0]
print FindSource("Slice1").SliceType.Origin
Render()

For the first test, I would like to change the Slice origin.
Unfortunately, the script gives me a segmentation fault using the
Python-Shell from within paraview and using pvpython it simply gives a
black picture.
I do not use the python trace state option as there are some settings
missing and the above approach would fit better into my daily working
style.

Would be nice, if you have a suggestion how to do this and how to change
the source file name!?

Thanks in advance!

 gets loaded.

 I've also tried to create a new reader instance with the file list as

 changed their Input property in case that were a reader. Then, created a
 new animation scene in the same way as AnimateReader does it in
 Utilities/VTKPythonWrapping/paraview/servermanager.py and tried again to
 loop over all files. Still not working.
 Saving the state file from pvbatch and loading it into ParaView

 Is there someone who accomplished loading a state file and manipulating

If there is a solution to this problem, it could also pose an
approximate alternative solution for those looking for support for live
data in PV, an issue discussed just recently here: By means of a timer,
file size or file inspection it would be easy enough to have Python
ensure the validity of an input fill, then re-execute the pipeline for
the new file, create a snapshot automatically and wait for the next file
to appear.

[Paraview] add buttons with custom filter and assign key binding

[Fabian Braennstroem]

Hi,

I have some questions to the gui handling :-)

Is there an option to add custom filters as buttons in the menu bar?
And is it possible to place custom filter into the 'common' subdirectory?
Are there plans for the future to allow some keybinding settings for the 
user?

Hello,

I just tested the povray exporter for glyphs. It seems, that the
exporter does not include the coloring depending on the variable!?
Maybe, I am missing some option during the export...
Would be nice, if you have a hint, how to export to povray using paraview!

Thanks in advance!

Re: [Paraview] Surface streamlines are slow

Hi Bastil,

Thanks!

Hi group,

I tried creating some surface streamlines as described in the wiki.
Process seemed to work but was extremly slow for me so I could not wait it.
I have large CFD models imported as ensight (~ 20 Million cells).
Paraview run for about five hours without an result for surface
streamlines from 50 seed points. I don't really know if this is normal?

Regards BastiL
