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
