Re: [Paraview] Saving as csv data

[Li, Teng]

Hi Utkarsh,

Thanks!

I have successfully use the "Cell Data To Point Data" filter and save a csv 
file with all the components I expected to see. 

Actually, I would like to process the three stress component data in the 
original VTK file. So I choose to save them as the CSV data. However, I have 
totally 118 time steps, thus 118 VTK files. If I save all of them and process 
each in the Matlab and finally show back in Paraview, that will be a huge 
amount of work. So I use python shell to access the data and process them. 
After some searching, I find some valuable codes:

1. 
>>> a =GetActiveSource()# First highlight the 
>>> stress vtk file in pipeline.
>>> a

>>> a.UpdatePipeline()
>>> rawData = servermanager.Fetch(a)
>>> data_cell = rawData.CELL_DATA_FIELD
>>> data_cell
>>> data_cell = rawData.GetCellData
>>> data_cell

>>> print data_cell


As we can see, this code only gives some simple information, not the actual 
stress data I need to process. I am wondering how I can access the actual data 
so I can finish all the calculation in Paraview. And since Paraview can read 
file series, so I can process the data once and change all of them in all the 
files. 

So my question is how I can get access to the stress data in the vtk file using 
python shell.

Best,
Teng

Teng,

In your attached VTK file, stress is a cell data i.e. associated with
each of the cells rather than the points. When you export data as CSV
you can only save points along with point data or cells data and not
both. If you want to save out stress associated with each of the
points, you can apply the "Cell Data To Point Data" filter first and
then save the result out.

Re: [Paraview] [EXTERNAL] Re: Paraview 5.4.1 error message & freeze

Sonya,
If nothing else works, use ParaView 4.4.0.  That release is a workhorse, and 
was the version before we updated OpenGL requirements.

Hello Cory & Paraview team,

I am just giving below a SUMMARY on the errors I encountered while working with 
ParaView.

Version 4.0.1 installed on my old (2013) 64-bit Toshiba laptop under Windows 7: 
works fine, shows images for model.vtk & glyph for data.vtk; does not freeze.

Version 5.4.1 just DOES NOT install on my old (2013) Toshiba laptop.

Version 4.0.1 installed on a new (2016) Dell laptop under Windows 7: shows 
images for model.vtk & glyph for data.vtk, but freezes while attempting to do 
full screen or just to drug the screen edge in order to increase screen with 
the following diagnostics:

Output messages
QWidget:: repaint: Recursive repaint detected.

Version 5.4.1 installed on a 2016 Dell laptop under Windows 7: shows images for 
model.vtk, BUT glyph for data.vtk STAYS EMPTY, and the application ALSO freezes 
while attempting to do full screen or just to drug the screen edge in order to 
increase screen, with no diagnostics.

- - - - - - -
So, for now I have to continue working with version 4.0.1, and it is fine, so 
far, for the learning purpose. To prevent freezing, I simply avoid to increase 
screen / full screen.

The  version 4.0.1 was my random choice, just the first version I saw available 
for 64-bit system.
Would you recommend for me to try any newer version?

Many thanks for your help,

Sonya Davydycheva

Thank you Cory,

For your prompt response. Good to know that the message is harmless.

My Paraview 5.4.1 just stops responding sometimes.

If it stops responding consistently after a specific event or sequence of 
events, please let us know. It shouldn't do that :-)

But, well, I installed on another (older) laptop an older version, 4.0.1 (5.4.1 
did not work there), and it does not freeze. So far, I think it is ok for my 
learning purpose.

Very good.

Both versions (on both computers) allow me to visualize my sample model.vtk 
file: in RenderView I can do Threshold, Slice and Clip and see some 3D 
pictures. But something is wrong with my other sample data.vtk file (or, with 
my approach?). It contains data points (3 coordinates) and the resistivity 
values assigned to them. When I open it, I can see only the resistivity 
colorbar, and I can add axes, but the image stays empty.
Threshold does not work at all (and even the colorbar disappears when I apply 
it).
Slice somewhat works, but it stays gray/empty and does not change as I move it 
along the box.
And when I am in "Slice" mode, pressing "Apply" removes the colorbar as well, 
and does not show anything meaningful.

Any idea how can I activate Threshold or Slice for my resistivity data.vtk?

I am beginner and suspect I just miss something simple...
Reading ParaViewGettingStarted-5.4.0.pdf and ParaViewTutorial54.pdf, does not 
help, so far.

I suspect that you do not have any cells in your 3-point data.vtk file. Without 
cells, there is nothing for ParaView to visualize. This is a common stumbling 
block for people trying to visualize point data.I suggest after loading your 
data applying a Glyph filter. It should show you three spheres colored 
according to your resistivity array. Now you should be able to apply the 
Threshold and Slice filters as you would expect.

Thanks,
Cory

Re: [Paraview] Saving as csv data

[Moreland, Kenneth]

Teng,

The issue is that your stress field data is associated with the cells and you 
are writing out the point data in your csv file. Thus, the stress data is not 
being written. There are two solutions, both with flaws:

Solution 1: When you get the dialog box labeled "Configure Writer 
(DataSetCSVWriter)" (after you choose a filename), change the option "Field 
Association" from "Points" to "Cells". If you do this option, you will only get 
the x, y, and z for the stress (labeled "stress:0", "stress:1", and 
"stress:2"). You will not get the x, y, z information for the placement of the 
points.

Solution 2: Before writing out the csv file, run the "Cell Data to Point Data" 
filter. Then write out the csv file with point data as you have been doing. You 
will get the x, y, and z for the stress (labeled "stress:0", "stress:1", and 
"stress:2") and you will also get the positional x, y, and z (labeled 
"Points:0", "Points:1", and "Points:2"). The problem with this solution is that 
it will alter the stress data slightly by averaging values of adjacent cells to 
points.

Also note that neither of these options will automatically write out the 
magnitude of the stress. To write out the stress magnitude, first run the 
"Calculator" filter to compute the magnitude of the stress vectors.

Re: [Paraview] Hardware for local install

[Utkarsh Ayachit]

Keith,

There's no easy answer for this, I am afraid. It depends on the type of
data and kind of processing you intend to do. A few things to note:

1. most data processing is done on CPU.
2. rendering, including rendering of image volumes using volume rendering
techniques as well as surface/polygonal rendering uses GPU.

What is the type of data or kinds of processing you plan to do? Maybe that
can help weigh the scale in direction over the other.

Re: [Paraview] Animate Clip - Cue does not have domain or property set!

[Utkarsh Ayachit]

That's indeed a bug.  Here's a fix:
https://gitlab.kitware.com/paraview/paraview/merge_requests/1955

For your build of ParaView (assuming you are using 5.4), you can load the
adding XML as a plugin and then create the filter. The XML will override
the builtin definition for the proxy and hence will overcome the issue.

  Set the origin of the plane.

  
  


  Set the normal of the plane.  For many filters this also sets the side
  of the plane that is of interest.  The normal points towards the
  "outside" of the plane.

  
  


  Specify the offset to shift the origin along the direction of the normal by.

[Paraview] Hardware for local install

[Draghi, Keith]

Hi All,

I am looking for some recommendations or running Para View on local hardware, 
specifically geared to 3d rendering.  Should I be looking at more GPU vs 
processor vs memory?

Thank you.

Re: [Paraview] Paraview 5.4.1 error message & freeze

[Sonya Davydycheva]

Hello Cory & Paraview team,

I am just giving below a SUMMARY on the errors I encountered while working
with ParaView.

Version 4.0.1 installed on my old (2013) 64-bit Toshiba laptop under
Windows 7: works fine, shows images for model.vtk & glyph for data.vtk;
does not freeze.

Version 5.4.1 just DOES NOT install on my old (2013) Toshiba laptop.

Version 4.0.1 installed on a new (2016) Dell laptop under Windows 7: shows
images for model.vtk & glyph for data.vtk, but freezes while attempting to
do full screen or just to drug the screen edge in order to increase screen
with the following diagnostics:

Output messages
QWidget:: repaint: Recursive repaint detected.
-

Version 5.4.1 installed on a 2016 Dell laptop under Windows 7: shows images
for model.vtk, BUT glyph for data.vtk STAYS EMPTY, and the application ALSO
freezes while attempting to do full screen or just to drug the screen edge
in order to increase screen, with no diagnostics.

- - - - - - -
So, for now I have to continue working with version 4.0.1, and it is fine,
so far, for the learning purpose. To prevent freezing, I simply avoid to
increase screen / full screen.

The  version 4.0.1 was my random choice, just the first version I saw
available for 64-bit system.
Would you recommend for me to try any newer version?

Many thanks for your help,

Sonya Davydycheva
