[Paraview] Visualizing load paths

[Sellmann, Kai Asaad]

Dear Paraview Community,
I have succeded to import my FEM Data (Nodal Coordinates, Element Connectivity 
and Nodal Tensions) into Paraview via a self written *.vtk-file.
Now that I finally have my Force Vectors I want to use the stream tracer 
filter. But whatever I do ülaying around with the stream tracer settings, 
nothing happens.
I don't even get an error message or anything like that. Is there any 
additional documentation about the stream tracer filter? Anything else I could 
read and can't find on google?

I'd be grateful for any hints, help or critics =)

Thanks a lot!
Asaad

[Paraview] Contours of integer array

[Schlottke-Lakemper, Michael]

Hi folks,

I would like to visualize an integer array of an unstructured dataset based on 
voxels, which contains MPI rank ids generated by a filter we use. To achieve 
this, I plan to somehow extract the “sharp” interfaces, similar to what the 
contour filter does, to obtain a visual representation of the domain 
decomposition. However, for the contour filter, I first have to call “Cell data 
to point data”, which smears out the previously sharp interfaces and causes 
connectivity problems of the resulting contours, as in some areas the domain 
decomposition features are very small.

Is there another way how I could extract these contours? Please note that I am 
not using vtkProcessId but rather an own integer array.

Thanks a lot in advance

Michael

Re: [Paraview] Contours of integer array

[Schlottke-Lakemper, Michael]

Maybe some visualization might help to illustrate the problem. This is what the 
domain decomposition looks like for two domains:

[cid:5C5D6EE8-569B-4469-93BF-E838F51706B8@aia.RWTH-Aachen.DE]

There are only two domains with values 0 and 1, respectively. I then select & 
apply the “Cell Data to Point Data” filter, then the “Contour” filter with only 
one isosurface set to “0.5”. However, in this example, the result is a blank 
screen, i.e., no visible output from the Contour filter.

In another example, I get the following result:
[cid:43435313-C9BC-46AB-94F7-145F6A981F56@aia.RWTH-Aachen.DE]

The sharp, colored interfaces of the integer array in the back is clearly 
visible. In this case, there are 5 domains (values [0,4]) and I used 0.5, …, 
3.5 as the isosurface values in the contour filter. While in this case I 
actually get an output (white lines), they follow the fuzzy output of “Cell 
Data to Point Data” and I am not able to reconstruct the sharp interfaces.

To conclude, my problems are actually twofold: I would like to find out how to 
restore sharp contours, and - if that does not work - at least how to make this 
approach work for all datasets I am looking at.

Again, thanks a lot in advance, and please excuse my double posting...

[Paraview] different data ranges

[Schmied, Christopher /DZNE]

Dear all,

I am new to paraview.

I want to visualize and compare two image stacks with different bit depth (8 
and 16-bit).
Thus two different data ranges. Is there a way to overcome the default 
behaviour of paraview to use the same color transfer function?

I found two related posts here, but I somehow cannot make this work for me.

Re: [Paraview] Contours of integer array

[David E DeMarle]

Could try threshold, or nearly equivalently clip by scalar, followed by
surface filter.

Another option is the material interface filter. That requires unstructured
grid input and an integer or idtype material array. Clip its output or use
opacity to see inside since its external surface looks the same as its
input's.

Re: [Paraview] Contours of integer array

[Schlottke-Lakemper, Michael]

Hi David,

Thanks for your answer. From what I understand, your suggestions allow me to 
extract the surface for a single domain. However, what I am really looking for 
is something like in the second example, i.e., where I get lines representing 
the domain boundaries between *all* domains at once. I just want them to align 
neatly with the actual boundaries and not have them diluted by the 
Cell-to-Point filter. Any idea how I can achieve that? Or maybe I just 
misunderstood you…

Re: [Paraview] Contours of integer array

[David E DeMarle]

Extract region surface will do all domains at the same time.

What it does is iterate over all cells and extract the faces of the cell
for which either their is no neighbor or the neighbor cell has different
material.

Re: [Paraview] different data ranges

[Cory Quammen]

Christopher,

You basically need to have different names for your 8 and 16 bit data
arrays to be able to use color maps with different ranges.

You tried the Calculator trick to rename one of your arrays? Could you walk
through what you tried that isn't working?

Thanks,
Cory

Re: [Paraview] Contours of integer array

[Schlottke-Lakemper, Michael]

Hi David,

ah, ok. However, in this case I’m wondering what I am doing wrong here: If I 
use the Extract Region Surface filter, my dataset looks just like before. Do I 
need to create an array with a certain name that contains the information on 
which the regions are extracted? And does this work also for 2D (unstructured 
grid with vtkQuads) or only in 3D?

Sorry for being so slow :-/

Re: [Paraview] different data ranges

[Cory Quammen]

Christopher,

Adding the paraview list back so that others may benefit from or contribute
to the discussion.

I think the advice to leave the function blank wasn't quite right. What you
actually want in the function is the name of the existing array in your
data set. You can get a list of the names in the Scalars or Vectors pop-up
menu at the bottom of the calculator controls, or you can just type in the
array name. For example, to rename from 'ImageScalars' to 'Result', you
would leave the Result Array Name as 'Result' and enter 'ImageScalars' in
the function.

HTH,
Cory

Re: [Paraview] different data ranges

Dear Cory,

ah ok! Good that works now. I also needed to change the data array in the 
coloring section from my “MetaImage” to “Result"
Awesome! Thanks a lot!

Re: [Paraview] problems using pvbatch in frozen build

certainly seems like a bug worth fixing. let me know if you want me to

Thanks Utakarsh. It sounds like it may be possible to work around the

Re: [Paraview] ParaView 5.1.1 Release Plans

[Hahn, Steven E.]

I encountered issues building ParaView 5.1.0 with VTK_USE_SYSTEM_HDF5=ON and 
CMake 3.6. The issue with FindHDF5 was reported by another user on the CMake 
mailing list (http://public.kitware.com/pipermail/cmake/2016-July/063908.html) 
and on OS X I was able to work around it by setting the HDF5_ROOT variable. 

I also encountered linker errors that go away after cherry-picking VTK commit 
351d0a6d1ce13daef7e52ed988f843aae0ff9fbf 
(https://github.com/Kitware/VTK/commit/351d0a6d1ce13daef7e52ed988f843aae0ff9fbf).
  Would you please add a fix for the HDF5 linking errors in ParaView 5.1.1?

Folks,

Since there we a couple of crucial issues reported after the 5.1.0
release, we are planning on putting out a 5.1.1 patch release.

Currently, this will include the following fixes:

1. Address issues with depth peeling not working as expected in
client-server mode.
2. Address issues with ExodisIIReader not loading certain variables.
3. Address issue with nested lists in OpenFOAM
4. Address issue with "?" button not working in ParaView binaries.

Is there anything else that's can qualify as critical that should go
in this patch release? Note the 5.2.0 release in planned for SC16 i.e.
Oct/Nov.

If there's nothing else, I think we have fixes for almost all of
these, so we can put the release out early next week.

That's already on the `release` branch which will become 5.1.1. There
are a few more issues with it that we are currently tracking down, but
yea, it should get included in the 5.1.1 release.

Re: [Paraview] Invisible volume rendering in client/server mode

[Utkarsh Ayachit]

Odd. I wonder if it's driver related. Did you build ParaView with
VTK_RENDERING_BACKEND set to OpenGL2? Also, "-tdx"/"-tdy" could indeed
slow things down as it's now rendering for a tiledisplay rather than
for a client. The rendering works in that case, since the client is
rendering on it's own. Also what is the datatype you're rendering? I'd
suspect it's an unstructured grid or a multiblock of unstructured
grid.

[Paraview] VTK data partition

[张江]

Hi,

I use vtkDistributedDataFilter to partition the unstructured data. It seems 
that each process gets a data partition and does not know any information about 
other data partitions.
So my question is, after the partitioning, given a point, how can I know which 
process owns it? Or simply how can I know whether it is inside the entire 
domain?

Best regards,

Thank you Utkarsh,  that did the trick.

Re: [Paraview] Can a collaborative client share a pipeline without creating a view itself?

[Peter Debuchev]

Dear Utkarsh,
is there any chance that this issue is looked at during the upcoming
hackathon?

Re: [Paraview] Invisible volume rendering in client/server mode

[Gunnar Jansen]

Oh, I forgot to mention the data type in my previous post.
You are indeed right, it is an unstructured grid. In order to make sure it
is not related to my input files, I tried with the example case XX as well
with the same results.
ParaView was built with the OpenGL2 rendering backend, as this seems to be
the new standard also with the pre-compiled clients.
I think this is not a MPI issue, as also starting only a single process
does not solve the problem.
