[ESPResSo-users] Basic Question about using LB

I am trying to simulate a quasi-two dimensional mixture suspension composed by rigid dumbbells and spheres.

I am planning to use LB fluid and LB as a thermostat. However just to be on the safe side, I would like to ask you the following:

a) It is possible to use LB fluid for a no-cubic box. I want to use a box with different length in z-direction. I just want/need a layer of fluid in z-direction to cover the particles.

b) Because of the periodicity of the system, I was wondering if LB fluid can handle partial periodicities (1 1 0) 

c) Finally, there are experimental results  where a uniaxial anisotropic particle is characterized by two translational hydrodynamic friction coefficients, Da and Db, respectively, for motion parallel and perpendicular to its long axis. Could you share some thought about it will be possible to observe such behavior using LB fluid.

Thanks a lot in advance,

Salvador H-V
