We present an efficient open-source implementation of the multiparticle collision dynamics (MPCD) algorithm that scales to run on hundreds of graphics processing units (GPUs). We especially focus on optimizations for modern GPU architectures and communication patterns between multiple GPUs. We show ...
Fluid–solid boundary conditions for multiparticle collision dynamics - Abstract - Journal of Physics: Condensed Matter - IOPscienceWhitmer, Jonathan KLuijten, Erik
Multiparticle collision dynamics (MPC), a particle-based mesoscale simulation technique for complex fluid, is widely employed in nonequilibrium simulations of soft matter systems. To maintain a defined thermodynamic state, thermalization of the fluid is often required for certain MPC variants. We invest...
In 1984 Erpenbeck observed a shear-induced alignment of particles into strings in nonequilibrium molecular dynamics simulations of shear flow in the hard-sphere fluid. In this paper we show that this effect arises from the use of a therm... DJ Evans,GP Morriss - 《Physical Review Letters》...

Poland We review the perturbative approach to multiparticle production in hard collision processes. It is investigated to what extent parton level analytical calculations at low momentumcut-off can reproduce experimental data on the hadronic final state. Systematic results are available for various ob...
2. Multiparticle Collision Dynamics The particle system contains N identical point particles of unit mass that are distributed uniformly over cells on a regular three-dimensional lattice. Each cell, ξ, contains n particles on average. At discrete time intervals, ∆t, the continuous positions, ri...
Molecular-dynamics-coupled multiparticle collision dynamic (MPC-MD) simulations have emerged to be an efficient and versatile tool in the description of mesoscale colloidal dynamics. However, the compressibility of the coarse-grained fluid leads to this method being prone to spurious depletion ...
Multiparticle collision dynamics, a particle based mesoscopic simulation technique, has found a wide spread use in the simulation of complex fluids such as colloidal suspensions, polymer solutions, and reactive flows. It has been shown that at macroscopic length and time scales correct hydrodynamics is...
