I’m using Paraview to visualize particle trajectories. The trajectories are written to disk in ExodusII format using libMesh (finite element library). When I visualize the particles, their trajectory is random as shown in Paraview, however, they should be moving along a straight line (based on simulation’s raw output of particle center). Has anyone met this issue before or could provides some hints to address it?
Attached are the movie showing particle’s random trajectory visualized by Paraview, and the trajectory files in ExodusII format.
Thanks for your reply. I did the same steps as yours, but the particle moves randomly.
I tried ParaView 5.5.2 and 5.6.0-RC2 on a Macbook with macOS High Sierra version 10.13.6, and also tried ParaView 5.1.2 on a linux machine (Fedora 4.5.5), they all show the random trajectory, instead of the small, linear amount movement.
Wow, that’s weird. I get the same behavior when I try on Mac.
I’m not sure why you appear to get the files out of order. One thing I notice is that your Exodus files do not have a time step in them. That might be throwing the reader off. Can you write out your files with at least one field for a time step with a particular time value?
