Dear Foamers:

I hope all of you are fine.

I am trying to solve the particle from 0.1 micro-meter to 100 micro-meter using Lagrangian tracking method. But even the time step is very small, the particle doesn't move .

I used the numerical method which is in icoLagrangianFoam to evolve the particle motion and for the flow field, I use LES.

I guess maybe the accuracy in the space or time is not enough.

Would you please give some advice on it or some better numerical method for particle tracking?

Thanks and best regards.
