Two Dimensional Simulation of Laminar Flow Around Two Bodies in Relative Motion [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2012 In this paper an efficient dual time implicit approach is used to solve viscous laminar flow around two bodies with general motion. Therefore, the grid includes a background grid and two sets of grids around the moving bodies.

A parallel dynamic overset grid framework for immersed boundary methods
CoRR, 2019 A parallel dynamic overset framework has been developed for the curvilinear immersed boundary (overset-CURVIB) method to enable tackling a wide range of challenging flow problems. The dynamic overset grids are used to locally increase the grid resolution near complex immersed bodies, which are handled using a sharp interface immersed boundary method ...

Journal of Computational Physics, 2022 We use the energy method to study the well-posedness of initial-boundary value problems approximated by overset mesh methods in one and two space dimensions for linear constant-coefficient hyperbolic systems. We show that in one space dimension, for both scalar equations and systems of equations, the problem where one domain partially oversets another ...

Multi-Size-Mesh, Multi-Time-Step Algorithm for Noise Computation on Curvilinear Meshes [PDF]
, 2013 Aeroacoustic problems are often multi-scale and a zonal refinement technique is thus desirable to reduce computational effort while preserving low dissipation and low dispersion errors from the numerical scheme.
