If you want to release multiple particles, you need to have multiple seed points. The type of movement through a flow field is important to determine the type of animation you wish to perform. If it is streamtraces, then you put in multiple points and let them go in a single solution. If you are tracing the particles through time, you will have to do something entirely different. I did this with a 1.5TB solution, containing 750 2GB solution files. If you can load the entire solution into Tecplot, place the particles the same way you do streamtrace seed points, but then track the particles using the analyzer not the streamtracing animation dialog. If you cannot have all the solutions in memory at one time, you will have to load at least 2 solutions. For the first solution, initial start, place the seed point with the streamtrace mechanism. Then, output a frame for an animation file; I typically use mpeg. Then track the particle movement for one time step to the next solution. and output another frame. At this point, you need to extract the particle locations to zones or a zone. Delete the particles, delete the first solution, load the next solution, and place the particle beginning points from the extracted zone. Advance one time step, output the frame, extract the new particle points to another zone, and continue this process through the entire set of solutions.
