Large Time Step and Overlapping Grids for Conservation Laws
… conservation laws. We also consider a method of overlapping spatial grids for which variants have proved to be an important consideration in large scale applications. In practice we often run into grids which have a fairly large range of cell sizes -- some cells may be relatively large compared …

Highly scalable solution of incompressible Navier-Stokes equations using the spectral element method with overlapping grids
We present a highly-flexible Schwarz overlapping framework for simulating turbulent fluid/thermal transport in complex domains. The approach is based on a variant of the Schwarz alternating method in which the solution is advanced in parallel in separate overlapping subdomains. In each domain, the …

Advances in parallel overset domain asembly
… simulations, information is transferred between overlapping grids via interpolation. Domain Assembly is the process that governs the location of intergrid boundaries and how the solution is interpolated across grids at those boundaries. Performing Domain Assembly in a distributed environment is …

A theoretical study of the sea breeze
… a finite difference model based on a series of overlapping grids. The principal effect of the nonlinear terms is a landward advection of the sea breeze circulation.

Time-stable high-order finite difference methods for overset grids
Overset grids provide an efficient and flexible framework for implementing high-order finite difference methods to simulate compressible viscous flows over complex geometries. Although overset methods have been widely used to solve time-dependent partial differential equations, very few proofs of …

Numerical solutions of the general relativistic equations for black hole fluid dynamics
… be built around the Adaptive Mesh Refinement and overlapping, curvilinear grid methodologies in order to extend these schemes to the efficient solution of two and three-dimensional problems. When implementing the algorithm, we will use previously written code libraries, where appropriate, to avoid …

Propeller Noise Prediction of an Urban Air Mobility Vehicle in Urban Environment
… complex transition kinematics through dynamic overlapping grids. However, its effectiveness for aeroacoustic prediction in OpenFOAM has not been previously demonstrated.</p> <p>To address this gap, a comparative study was conducted for a Joby-scaled five-bladed propeller at an 80° tilt angle …
