To understand the relations of these types of mesoscale simulation techniques in more detail, we propose two new methods, which are intermediate between DPD and MPC-DPD with multibody thermostat (DPD-MT), and MPC-Langevin dynamics (MPC- LD). The key features are applying a Langevin thermostat to the relative velocities of pairs of particles or multi-particle collisions, and whether or not to employ collision cells. The viscosity of MPC-LD is derived analytically, in very good agreement with the results of numerical simulations. Copyright (c) EPLA, 2007.
