Date: Mon, 26 Sep 2011 04:07:38 -0700 (PDT) I did not mean lattice boltzmann by BD. By BD I meant Brownian Dynamics. In general, for accuracy in dynamics, one uses hydrodynamic interaction in brownian dynamics simulation. I was wondering whether hydrodynamic interaction is invoked in gromacs implementation of brownian dynamics simulation. Please keep correspondence on the mailing list. So how do want to include hydrodynamic interactions into BD ? I think the Lattice-Boltzmann method is a way to do this isn't it ? /Flo From: Dommert Florian domm...@icp.uni-stuttgart.de To: Sanku M msank...@yahoo.com; Discussion list for GROMACS users gmx-users@gromacs.org Sent: Monday, September 26, 2011 3:38 AM Subject: Re: [gmx-users] BD with Hydrodynamic interactions?
