Dear developers,

I would like to incorporate magnetic particle dynamics (particles have its volume, collision detection between particles) in the lattice Boltzmann flow. My plan would be to connect the features

- Dipolar all-with-all and no replicas (DAWAANR)
- object-in-fluid or/and virtual sites
- LB

The magnetic particles should interact with the fluid and vice verca. And of course the particles should interact via dipolar forces.

Would it be best to use virtual sites or the object-in-fluid implementation? Using virtual sites the fluid interaction of the virtual nodes need to be implemented. And the particle in the center of mass could handle the dipole interaction. Object-in-fluid would have already the fluid-particle interaction. Maybe a combination of both methods would be sufficient.

Is there anyone who is already working on the subject or a similar one? Maybe without the magnetic part, just virtual sites in the LB flow. Is it maybe already in developement?

I would be happy to get comments on the topic and to share ideas.
