Hi Tom and Utkarsh, I finally had time to take a closer look. There is a corresponding merge-request https://gitlab.kitware.com/vtk/vtk/merge_requests/2716
Cheers, /mark ________________________________________ From: Tom Fahner <tom.fah...@gmail.com> Sent: Monday, April 3, 2017 3:24:19 PM To: Utkarsh Ayachit Cc: Mark Olesen; ParaView Subject: Re: [Paraview] Native OpenFOAM reader for ParaView 5.3.0 has some weird visualization issues. Hi Utkarsh, I finally had some time to look into this issue a bit further. I have a testcase for you of an Ahmed body that also shows the weird missing of the data. The case with some intermediate result (approx 400 MB) can be found here: https://we.tl/ZZwy4ZGL1K The case without that result (approx 125 MB) can be found here: https://we.tl/3dSqgyd4zG Hope this helps in finding the issue. Please let me know if you need more information. Best Regards, Tom 2017-03-16 13:25 GMT+01:00 Tom Fahner <tom.fah...@gmail.com<mailto:tom.fah...@gmail.com>>: Hi, Let me check if that is possible, I do not think I can share this particular one. I will come back to you. Tom 2017-03-16 13:12 GMT+01:00 Utkarsh Ayachit <utkarsh.ayac...@kitware.com<mailto:utkarsh.ayac...@kitware.com>>: Tom, Do you have a dataset to reproduce this issue? There were changes in the reader in this past release, so it's conceivable that it introduced a bug.
