I am trying to visualize flow of a simulation of an aircraft in ParaView. I can plot simple contours without any problem, but when I attempt to plot streamlines over a slice, my ParaView just crashes. I get the following error:
(318.626s) [78588DFF7640]vtkFindCellStrategy.cxx:26 ERR| Initialize must be called with a non-NULL instance of vtkPointSet
error: exception occurred: Segmentation fault
Previously, I did same thing in v5.11 without any problem and I just updated it to v5.12. What might be the reason for this, and how can I fix this issue? Am I missing any modules in my system?
@mwestphal Thanks for reply. I have uploaded the files in the attached google drive link. This folder contains volume data as well as wall data (if requires). I would like to reproduce: (i) streamlines around the wing at a slice normal to Y axis at any cross section (for instance at y ~ 578) (ii) streamlines over the whole wing in z-plane.
Thank you, I appreciate it. In the attached figure, you can see a velocity magnitude contour on a slice that is normal to the y-axis at y = 578 units. I would like to add streamlines to this slice to better visualize how the streamlines behave around the wing.
@mwestphal, thank you very much. Although I couldn’t get anything meaningful from Surface Streamlines, the surface LIC option is working well for me.
