Dears,
I'm learning to use ParaView, my ParaView version is 4.2.0 64-bit based on windows. My vtk data is in the attachment, with a picture of the calculated object. I had consulted several similar threads in the forum and implemented their method, but still can't plot the streamline. Here are the reference threads.

For the second reference, I can repeat the result with vtk data attached by wyldckat. What's more, my ParaView is always stuck in Delaunay3D filter, which I really don't understand. Does this filter calculate a lot or may my data have some problems to implement it? Really need your help. Thank you so much.

PS: Cos the data file is too big for attachment, I upload to the net storage. Here is the link.
