Lagrangian Particle OpenFOAM
 

Hello. I made a simulation of the motion of Lagrangian particles using the "particleFoam" solver. Each particle was counted separately and then I put them on one graph. It seems to me that I got the wrong trajectories because the particles practically do not rise along the "x" axis. What could be the mistake?

P,S, At the beginning I counted the inviscid gas using "rhoCentralFoam". Then I took the velocity and density distribution and worked with the "particleFoam" solver.

Have you tried running the simulation with "coupled" as true? I think this is the issue.

thanks for the reply. I consulted with some people and realized that I got a fairly correct result. And what is the "coupled" setting. And what it affects. When I ran the simulation with "true" I didn't get the change.
