Hi Andy, I followed your instructions and have had some success but not completely :)
Here is what I did: 1) My input data has a time-dependent X velocity and a Y velocity and the mesh information 2) I use the "Calculator" tool to create a "velocity" vector using "x_velocity*iHat + y_velocity*jHat" 3) With "Calculator1" active, I click on Streakline (Streakline filter doesn't show up with my initial data as, I guess, there are no vector fields there) 4) A pop-up window comes: for both the "Input" and "Seed Source" I choose "Calculator1" 5) Then "Streakline1" appears in the pipeline. I change Termination time to a non zero value. With the "Calculator1" and "Streakline1" "eye" activated in the pipeline, I click on the play button 6) I don't see any streaklines. Only the velocity contour movie continue (and much slowly than it does without the streakline filter on). 7) I don't see the option of where can I decide the point of origin of the streaklines. Any sugggestions?
