Hi, I have a paraview 3.14 under 64-bit Win7. I have a multi-zone cgns file (say 10-zone or more) with about 6 million points. The grid is curvilinear and I used calculator to do the coordinate convert, thing are good. I use calculate the velocity vector with calculator also and I do get the velocity vector.
(1) When I apply the stream tracer filter, I got nothing. The number of point and cell are zero. I think the connectivity of structured grid is explicit. I have no idea & I want to know what is the necessary input for a stream tracer filter to get streamline? (2) I also tried glyph filter to see what I got for the created velocity vector. The result is wried - I only have 50K points left. All the points stay at the outline of the curvilinear grid or the edge face. Any idea? Thanks a lot! Mei Chen
