We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

In my experiment, the particles were initially placed at the bottom of the stirred tank before the mixing process began. I would like to replicate this setup in my simulation as well.

I have tried coarsening the mesh to ensure that the mesh size is larger than the particle size, but this has not been successful.

What do you think about the possibility that stochastic collision is not suitable and is causing the unphysical behavior I am observing? Could I assume that particle collisions can be neglected and perform a one-way coupling simulation? The total particle volume is 1.25% of the fluid volume.
