| Outline of Final Research Achievements |
In the nonlinear flow behavior exhibited by polymer fluids, it is important to develop a multi - scale simulation method to solve by combining microscale and macroscale dynamics because microscale molecular motion affects macroscale flow behavior. In this study, we deal with the nonsteady state and consider the method of statistical processing to suppress the microscale fluctuation on the ensemble average and the moving time average method. We also considered the handling of the boundary condition of molecular dynamics simulation which is necessary when microscale simulation is replaced with molecular dynamics simulation.
