(YIP-10) Efficient and Robust High-Order Methods for Fluid and Solid Mechanics

Abstract

The goal of the project was to develop new numerical schemes and solvers for high-order accurate simulations of problems in fluid and solid mechanics. Three main areas were addressed the high computational cost of existing methods, their lack of robustness, and the need for new high-order mesh manipulation algorithms. The project has led to significant developments in so-called Line-DG and IMEX based numerical schemes, new formulations for problems with deforming domains, artificial viscosity based stabilization, and mesh deformation using a nonlinear elasticity analogy. The results were applied to a number of important real-world problems, such as drag prediction for turbulent flows, flapping flight with fluid-structure interaction, aeroacoustics problems, and transonic/supersonic flow problems. The findings were disseminated through a wide range of publications, presentations, and public domain software.
