have you tried in 3D?
I recommend DPMFoam as a good Lagrangian coupled solver, or IcoUncoupledKinematicParcelFoam if you only need particles as trackers.
If your particle is larger then the cell...

I would use salome to create a tet mesh and convert to OpenFOAM (some nice tutorials on youtube).
However, I use hex mesh and snappyHexMesh so I can't help you here.

Good Luck!

4-way coupling of interFOAM to Lagrangian Particle Cloud

Hi all,

OK I managed to do the 4way coupling for my version of interMixingFoam in agreement with DPMFoam, and the Goldschmidt test case looks fine. However, I get a shift in phase concentrations...

Thanks Alex!
What I can't understand is how you get two-way coupling when you include the particle momentum neighter in the UEqn nor in the pressure equation, only in the momentum predictor which...

Hi, do the particles injected influence the temperature field?

Of course, implementing your custom injection is the best way! But maybe you want to compare results then by running your case...

interFoam: lagrangian particle tracking method by swak4Foam

Hi Sebastian,

did that work well? Could you share some experience about coupling lagrangian particle tracking using swak4Foam? I used to run coupling via CFDEM to LIGGGHTS, but now I want to model...
