 May 5, 2003, 09:42 Re: Streaklines #2 Vincent Guest   Posts: n/a Hi, If you just want to follow a particle, you have to create a point at the location of the particle you want to follow and then create a streamline based on this point, you can do the same with a line or a plane. You have all informations in the CFX help and you can try the tutorial 3.

In transient flow, streamlines are the path a massless particle would take if the flowfield of that instant in time is used, and streaklines are the path the massless particle would take if the flow field is allowed to change with time. That's a physical description, you will probably find a more mathematical description in your textbook. CFX 5.5 can do streamlines in steady state and transient flow, and CFX 5.6 will do particle tracking (with and without mass) in steady-state flows. I believe you will have to wait until CFX 5.7 for true streaklines! Regards, Glenn Horrocks
