I have some positions data of a large number of particles over a large number of iterations. Visualizing everything at once over all iterations is therefore a bit of a hassle. I was wondering if there were any possibility to apply some initial filter that would be applied for all iteration e.g. track only particles that start in a given area ?
Any chance someone knows the solution ? I guess tracking only some specific particles in time is something elementary but I can’t find the way to do that.
My problem is that the Clip solution will clip on a given spatial region of the domain and this for only one timestep. What I would like to do is follow over all timesteps only particles that started for instance in region x>0.5 & x<0.75 or only particles whose initial velocity where say vel=1. So I would tag these particles initially and follow only them even though they go out of the inital region of interest or if they change their velocity. Is this possible ?
It looks like your number of points and point idexing is not changing over time also your point indexing is spacially logical, so extract points based on their ID should work perfectly.
Edit → FindData → Find Points → ID is between → the values you want
Oh great, I’ll look into that. Thanks again. I’ve recently heard you’re giving some introductory classes at my institute so I’ll ask to follow it. I still have some remaining questions to use this great software
Hello,
Is this topic still live? I hope it is because I have an almost identical problem. I have similar time sequence of particle datasets – including particle coordinates (x,y,z), and also tag01=particle ID. I also want to select groups of different particles by their initial positions (not necessarily their ID – though that would be an equivalent solution if I knew particle ID’s by region) and then follow these same group in time. I would also like to color this group of particles for visual clarity – other groups of particles would have different colors.
I would greatly appreciate sharing the solution to this problem with you (or anyone) with complete example. At the moment, I can follow the entire set of 288 particles as Point Gaussian; but when I select the different groups of particles with different colors, something strange happens: some of the colors appear to randomly swap between some of the particles.
