Best Practice For Plotting Streamlines Around a Cylinder

ParaView Support

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.

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,

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.

Worked perfectly! Thanks a lot.
Last question, will the Nightly version be merged on the standard distribution?
Thanks a lot.

It is going to be picked up by the next ParaView release about 6 months from now.
