Lagrangian Particle Filter

Hi
I’m using the vtkLagrangianParticleTracking plugin on paraview and was wondering if I could find more information on the plugin. I would like to more about the equations/physics behind the implementation and corresponding controls we have access to through paraview. Especially, if gravity, drag, etc was implemented.

Also I notice that while plotting the lagrangian particle path on flow field changing in time, it shows the path at any given instant. Is this path integrated over time?

Hi @vrkssai

Well, I developped it.

The matida model indeed support gravity and drag.

Is this path integrated over time?

No, temporal support is not implemented in the LPT
