Dear all, since one of my mails with multiple questions went completely unanswered ( http://www.mail-archive.com/gmx-users@gromacs.org/msg15437.html ), let me try this time with more specific question.
Is there any chance of Dissipative Particle Dynamics (DPD) being incorporated in Gromacs as a companion (or even replacement) of Brownian Dynamics? According to the book "Understanding Molecular Simulation" by Frenkel and Smit (Second edition, 2002, page 467), Brownian Dynamics does not conserve momentum, does not obey Newton's 3rd law and hence does not recover correct hydrodynamic (Navier-Stokes) behaviour at large length and time scales, while DPD takes care of all these problems. In that case, wouldn't it be more appropriate to use this technique as a replacement of Brownian/Langevin dynamics? Regards, Suman Chakrabarty.
