[ESPResSo-users] Lattice Boltzmann and the discretized Oseen Tensor

[Vincent Ustach]

Heres another theory question :)

Following Alrichs & Dunweg 1999 and Usta 2005, I have found the proper offset for friction in Lattice Boltzmann. The one thing I do not understand about the offset is how the Oseen Tensor becomes discretized to

u_av = F / (g eta dx)

 Is there a reference I can follow that explains this?

Thanks,
