Hi,
Glad to hear that the changed interpolation improved stability in your case as well. I wrote a little illustration to the problem on the bug-report. It would be useful to clean up (remove) the...

That is correct, the particle

That is correct, the particle collision pressure in twoPhaseEuelerFOAM is implemented, in the classical model, as a diffusive term in the alpha equation. If you have access to, for instance, Enwald...

Hi Guanghao What is your time

Hi Guanghao
What is your time step? Packing simulations usually require a very short time step, on the order of 1e-5. For your case 1, note that in OpenFOAM, the particle-particle force has the...
