I have been reading about the options to track particles within a flow field using Paraview and I found two methods that are plausible. The firs is the Particle Tracer filter (I actually used the particle tracer filter to track particles with somewhat success), and the second one is the LangrarianParticleTracker (LPT). Although I was able to know the interpolation methods that the LPT filter uses to track the particles, I couldn’t find info about the interpolation methods that the Particle Tracer filter uses to determine the position of a particle that changes in time. Does this filter also uses the MatidaIntegrationModel? I also wanted to know where I can find some examples on how to implement the LPT filter.
I appreciate the information, and this may be a too of a simple follow up question but I just want to make sure. When you say static datasets, does it mean velocity fields that are invariant in time? So for example, I should not use LPT for a simulation of an open channel flow with time variant boundary conditions. Did I misunderstand you?
Mathieu, do you know where I can find the information about how the ParticleTracer operates? I would like to know how the filter determines the velocity of the position of the particle. Does it just use the cell velocity, or what kind of interpolation method uses to determine the change in position of the particle?
