“…Periodic boundary conditions are easily imposed, while open or solid boundaries require an appropriate treatment of the conservative, dissipative and random force. We refer the reader to Revenga et al (1999), Mehboudi and Saidi (2014) and references therein for a detailed treatment of boundary conditions. We have outlined the similarities between DPD and MD and the coarse-grained nature of it.…”

Abstract. The aim of this study is to simulate the self-assembly of the surfactant molecules with special chemical structure and bending sti ness into bilayer membranes using a mesoscopic Dissipative Particle Dynamics (DPD) method. The surfactants are modeled with special chemical structure and bending sti ness. To con rm that the novel model is physical, we determine the interaction parameters based on matching the compressibility and solubility of the DPD system with real physics of the uid. To match the mutual solubility for binary uids, we use the relation between DPD parameters and -parameters in Flory-Huggins-type models. Unsaturated bonds can change the sti ness of a lipid membrane, which is modeled by introducing a bond bending potential. To verify our model, we investigate the e ect of surfactant structure, like chain length and sti ness of the molecules, on the properties of the modeled membrane as area per surfactant. To validate our results, we also compare them with the theoretical calculations as well as with the experimental and other existing simulations results. We show that there is a good coincidence between all of the results.

“…The periodic boundary conditions are applied to fluid boundaries in the x and y directions. On the surface of solid walls, we applied Maxwellian reflection boundary conditions to yield the no slip boundary condition [Revenga et al (1999)]. The flow is driven by a uniform body force per unit mass applied to both fluid and RBC particles in the x direction.…”

This paper presents a dissipative particle dynamics (DPDs) method for investigating the movement and deformation of biconcave shape red blood cells (RBCs) with the worm-like chain (WLC) bead spring. First, the stretching of a RBC is modeled and the obtained shape evolution of the cell agrees well with experimental results. Second, the movement and deformation of a RBC in shear flows are investigated and three typical modes (tumbling, intermittent and tank-treading) are observed. Lastly, an illustrating example of multi-RBCs in Poiseuille flow in a tube is simulated. We conclude that the presented DPD method with WLC spring can effectively model the movement and deformation of bioconcave cells.
