Many-body dissipative particle dynamics (MDPD) offers a significant speed-up in the simulation of various systems, including soft matter, in comparison with molecular dynamics (MD) simulations based on Lennard–Jones interactions, which is crucial for describing phenomena characterized by large time and length scales. Moreover, it has recently been shown that the MARTINI force-field coarse-graining approach is applicable in MDPD, thus rendering feasible the simulation of complex molecules as in MD-MARTINI for ever larger systems and longer physical times. Here, simulations of various lipid membranes were performed by using the MDPD-MARTINI coarse-grained (CG) force-field (FF), relevant properties were calculated, and comparison with standard MD-MARTINI CG simulations and experimental data was made. Thus, insights into structural properties of these bilayer systems and further evidence regarding the transferability of the MDPD-MARTINI CG models are provided. In this regard, this is a natural next step in the development of the general-purpose MDPD-MARTINI-FF, which generally provides significant speed-ups in both computational and physical simulated times, in comparison with standard CG MD simulations.
