Hi Joao,
Did you use “Slice” Filter first?
If not, use it first. Then apply EvenlySpacedStreamlines2D on that.

Dear Ali, I did used the slice filter. I took z normal so to get a XY plane where to do the streamlines. Still go the error. I see after the calculator filter that I can choose for “showing” the 3 directions however the z direction shows values from 0 to 1.2*10^-38.
Can this be the reason, that is still a 3D vector?
Thanks a lot.
Joao
If you attach your case I hope I can help better.
Dear Ali,
I sent you a message. How can I share my case here?
Thanks a lot.
Best wishes,
Joao
When you press reply button, a box appears, above of which are some keys like Hyperlink , Emoji , Upload… . press upload and attach your file. your stat file is not enough. Make a minimum sized zip file including stat and your case.
Dear Ali, thanks once again for your help. This is the case. I shared like this as it is a quite large one (around 400 mb)
I tried to do a 2D slice at z=0 with normal (0 0 1) and plot the 2D streamlines
Thanks a lot in advance for any help.3D data
I tested the case, however unfortunately with no success. I also left a comment here in the hope that the issue be solved.
A fix for this issue is at:
https://gitlab.kitware.com/vtk/vtk/merge_requests/6436
It will take a few weeks for this fix to be picked up by ParaView, but it will be eventually in ParaView master.
Here is a picture I generated from that dataset.
Thanks a lot. I will have a look.
You are welcome.
Here is the paraview statefile I used
But you’ll have to wait for the change to be propagated to ParaView master or build ParaView from source using my VTK branch.

streamlines.pvsm (490 KB)
By the way, ParaView master is always available as binary installs on the paraview.org website. Go to downloads, and change “Version” to Nightly.
I believe that @danlipsa change are not available in the nightlies nor in master since his VTK branch is not even merged in VTK yet.
Hello Everyone,
Thanks a lot for the help!
I downloaded the new Paraview 5.8 but still got the same error. Has the change been pushed to the VTK branch? If not, is there any timeline?
Thanks a lot once again.
Best wishes,
João
Dear Mathieu,
Thanks a lot for the answer
I downloaded the ParaView 5.8 for windows 10.
I tried to run the data I provided but still got the same error (related to data not being on xy plane). I used the stateFile provided by Dan Lipsa above. Can you confirm that it has been merged?
Thanks a lot for all the help!
Best wishes,
João
Did you download a nightly like this one :
https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=nightly&type=binary&os=Windows&downloadFile=ParaView-latest-Windows-Python3.7-msvc2015-64bit.exe
?
Dear Mathieu,
Yes, exactly that one!
thanks a lot.
Best wishes,
João
I tried again, but still got errors. I used the data I provided before and the stateFile by @danlipsa
The error log is:

Make sure you use nightly not 5.8.0. I just tried and works fine.
There are a number of warnings
vtkMath.cxx:1314 WARN| Unable to factor linear system
but those don’t seem to affect the result.
