Hi, @kshitij, did you highlight the solution data? and if so did you highlight the correct one? if you highlight the one showing just the wing surfaces then this will not work because in that solution data only surface data exists:
This is a screenshot of your project with the filters:
If I tried to put the filter on the other ‘run standard’ solution set then this wouldn’t have worked, so you need one solution set with just surfaces and one with the internal mesh, putting the streamlines on the internal mesh.
Hope this helps, if not just tag me
