Parallel in Time Molecular-continuum Flow Simulation<\/u><\/strong><\/p>\n\n\n\n

Fluid flow phenomena play an important role across a spectrum of disciplines in science and engineering. Since experiments are not always an efficient or feasible way to study them, computer simulations of these phenomena have turned out to be one of the essential tools for progress in this area. However, computational fluid dynamics is a challenging field, especially when characteristics on multiple length and time scales need to be captured. Coupled methods are one way to simulate such a flow. A molecular-continuum coupling simulation software is given by MaMiCo, an open source coupling framework with modular software design for massively parallel execution on high-performance computing systems.<\/p>\n\n\n\n

Parallel-in-time integration allows to expand a coupled simulation to multiple temporal scales. An implementation based on a variant of the Parareal algorithm is presented here, where a Lattice Boltzmann solver is used as hydrodynamic predictor to supervise the microscopic system in time. This parallel-in-time coupled molecular dynamics-Lattice Boltzmann approach is a way to enhance multiscale flow simulations, leading to significantly improved scalability on HPC systems such as HSUper.<\/p>\n\n\n\n
