I am studying a plume impingement and visualizing my openFOAM plume results in paraview (only the last time step of my simulation). Since I wanted to calculate particle path according to the flowfield, also taking forces into account, and trying to do a one way coupling of the
flowfield and ground particles,I am using the lagrangian particle tracker.
However, I am having some issues in that. I am applying the lagrangian seed helper to my case .foam and specified the initial velocity as 0, along with a particle diameter, density, and initial integration time. Then I apply the Lagrangian Particle Tracker, selecting the velocity field as the input flow field and the Seed Helper output as the particle seeds.
The problem is, I can see the particles, but they don’t move…
It might be the initial velocity I put as 0? However, when I switch to flow interpolation, ParaView crashes.
Has anyone encountered this problem before, or does anyone know how I can resolve it?
Thank you for your answer!
I don’t know if stream tracer can be useful for me..I understood that it shows how massless particles move through a vector field, am I correct? While I want to take mass and density into account for the trajectories.
I see it’s a bit complicate and I couldn’t find any tutorials or tips, the only one I found explains what it does in a very general way but probably every case is different and I am doing something wrong which I don’t know…
