Default particles under diffusion model?

Pled is on a distinguished road
I want to model particles that are moving under a pure diffusion model.
Is that possible?

You can do a diffusion only additional variable. The additional variable can then represent the concentration of the particles.

If you want to do lagrangian particle tracking using only a diffusion model then you could probably hack the existing lagrangian model to do it - define a user drag law and set it to zero and replace it with a diffusion based model. Getting this to work might be tricky.
Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.
