Re: [Paraview] [EXTERNAL] Paraview 5.2.0: max time limit of 4095 for annotated .vtu file?

[David.Benn]

Thanks Alan.

Joachim Pouderoux replied shortly before you did, asking if I was willing to 
create a merge request and also noting that since this is a VTK related issue, 
it should be reported to the VTK tracker instead.

I'm happy to create a merge request (I'm assuming we're talking about a 
GitHub/Bitbucket style git pull request), but should we instead be doing this 
via the VTK gitlab rather than Paraview as Joachim mentions?

Alan, Joachim: please feel free to let me know what procedure to follow and 
I'll go with that.

Thanks.

Hi Alan

Sure, will do. I have also tested a solution.

Looks like a bug.  Mind writing it up?  If you can give the developers a way to 
replicate the bug, it will significantly increase the chance it will be looked 
at...

Upon loading an annotated .vtu file with TimeStep annotations such as this into 
Paraview 5.2.0 (under 64 bit SUSE Linux):



I see the following:

[cid:image001.png@01D27C8B.17384DF0]

such that a maximum of 4095 time steps are available, as opposed to the 
expected 10,560 time steps.

When the non-annotated .vtu file is loaded, the expected number of frames are 
visible.

Is there some inherent limitation within Paraview that prevents more than 4095 
time steps from being loaded/visualised?

Thanks.

Hi,

Please keep the discussion on the mailing list so that anyone can
participate (also, stuff gets lost in my Inbox too).

The ParaView Catalyst Users Guide at
http://www.paraview.org/files/catalyst/docs/ParaViewCatalystUsersGuide_v2.pdf
has information on how to use the Live functionality. It's in Section 2.3.

Best,

Re: [Paraview] Ansys to ParaView

[Christopher Neal]

Hi Anxo,

I believe that Ansys supports the export of the solution(geometry and
results) to the EnSight format. Paraview can read the EnSight Gold format.
You may want to try to get ANSYS to export to EnSight and see if it works.

Re: [Paraview] data are read but not displayed

[Andy Bauer]

Can you share your data set? It will be difficult to diagnose without that
information.

Also, I'd strongly suggest upgrading to ParaView 5.2 instead of just the
release candidate.

Re: [Paraview] Point cloud to structured mesh

[Moreland, Kenneth]

The most direct approach is probably to use the Gaussian Resampling filter.

Another approach is to run the Delaunay 3D filter and then run the resample to 
image filter.

Is it possible to convert a point cloud to a structured mesh or an image stack

Re: [Paraview] Generate IDs

[Moreland, Kenneth]

Daniel,

As you have discovered, trying to “connect” data sets in this way after the 
clip filter is applied is problematic because it changes the locations of 
points and the structure of cells. It makes the grids no longer isomorphic or 
sub-isomorphic.

I would suggest one of two approaches. The first approach would be to combine 
all the data arrays into one data set before doing any of the extractions, 
thresholds, or clips. If all your arrays are on data sets with the exact same 
grid structure, then you can use the append attributes filter to combine the 
arrays of all these data sets into a single data set. Then the arrays will 
simply be available from the output of the clip.

If that approach will not work for some reason, a second approach is to use the 
resample with dataset filter. You can use this to sample the other data sets 
onto the clipped data set, which I think in the end gives you the effect you 
are looking for.

Subject: [EXTERNAL] [Paraview] Generate IDs

Hello, I want to

- open an unstructured grid,
- view a sub-volume using the Threshold filter that selects a certain material
- apply some Clip filters to remove unwanted parts
- select everything I am seeing now
- and create an "Extract Selection" filter that can be used for other vtk files 
containing the same unstructured grid but other data arrays.

But the "GenerateIDs" filter removes the material array from the dataset so I 
can't apply the Threshold filter anymore. I see the "Extract Selection" works 
only with the current IDs anyway that are different from the original cell IDs 
due to the Clip filters.

How can I have a filter that extracts a certain set of cells that I define and 
apply it to other .vtk files?

Thank you very much in advance,
Daniel

[Paraview] data are read but not displayed

Hi all,
I´m using: Paraview 5.2.0-RC1 , 64 bit.
All fields data are being read but not displayed, that is, fields displayed in 
only one color.When I use find data function, I can see the data.This happens 
only with: velocity & pressure.

Is it a bug or VTK has been corrupted or something else ?

Re: [Paraview] Writer plugin with selection of data arrays to output

[Sergey Alexandrov]

Hi Dennis,

Thanks for the suggestion! Honestly, at first I was skeptical about your
advice because it looked very
similar to my first solution that I outlined in the beginning of this
thread. However, as soon as I examined
the XML code for the PassArrays filter, I realized that this is exactly
what I need. It uses some built-in
ParaView magic to fill the list with data array names, so there is no need
for me to "inject" my custom
code to populate it. Neat!

Thanks again!

Cheers,
Sergey
