The numerical analysis of flow-induced structures of complex fluids is one of effective approaches for elucidating the mechanism of their complicated flow behavior. In this article, three examples of the numerical simulation of the flow-induced structure using the Brownian dynamics (BD) method and the multi-particle collision dynamics (MPCD) method are presented: (a) BD simulation of shear flows of polymer/clay suspensions, (b) MPCD simulation of shear flows of linear polymer solutions, and (c) MPCD simulation of bio-convection of phototactic microalgae in water. In these simulations, complex fluids are modeled by dispersion systems of basic elements of the fluid inner structure such as particles and model polymers, and their behavior is analyzed for the investigation of the flow-induced structure.
