报告摘要：
     Three high-fidelity, high-performance computational fluid dynamics (CFD) solvers for multi-physics and multi-scale simulation of complex flow problems in ship hydrodynamics and other fields will be introduced. The first solver employs immersed boundary methods on simple Cartesian grids. Fluid-structure interactions including wave-structure interaction problems will be demonstrated. The second solver is extended from the first one and based on orthogonal curvilinear coordinates for resolving the boundary layer and air-water interface at the same time. High-resolution simulations with up to more than 10 billion grid points running on up to more than 10 thousand CPU cores will be showed. The third solver adopts general structured grids for tackling complex geometries in practice applications and is still under development. The code structure and module design will be briefed. Some simple examples will be given for verification and validation. Future development directions will be addressed.

报告人简介：
      Dr. Jianming Yang is a full Research Scientist in IIHR-Hydroscience and Engineering and an Adjunct Associate Professor in the Department of Mechanical and Industrial Engineering at the University of Iowa. He obtained his B.S. in 1996 at Wuhan University of Hydraulic and Electric Engineering, and M.S. in 1999 at Nanjing Hydraulic Research Institute. He worked as an Assistant Engineer at the latter until 2001. In 2005 he received his Ph.D. degree in Mechanical Engineering at the University of Maryland, College Park. Since then he has been with IIHR as the principal code developer of the next-generation CFD Ship-Iowa software, a world-renowned CFD solver package for ship hydrodynamics research and applications. His expertise includes immersed boundary and Cartesian grid methods, level set and fast marching methods, strong coupling schemes for fluid-structure interactions, and massively parallel algorithms. Recently, he has been focused on developing high-fidelity, high-performance, multi-physics, multi-scale CFD solvers for practice applications in ship hydrodynamics.
