▪ Abstract We review artificial boundary conditions (BCs) for simulation of inflow, outflow, and
far-field (radiation) problems, with an emphasis on techniques suitable for compressible …

Perhaps the defining feature of waves is the fact that they propagate long distances relative
to their characteristic dimension, the wavelength. This allows us to use them to probe the …

We describe a new, efficient approach to the imposition of exact nonreflecting boundary
conditions for the scalar wave equation. We compare the performance of our approach with …

A new scalable high-resolution CABARET MILES method coupled with a porous Ffowcs
Williams–Hawking formulation for far-field noise modelling is applied for the computation of …

Publisher Summary This chapter reviews the Maxwell's equations in the time domain and
discusses boundary conditions, various simplifications, and standard normalizations. The …

The method of difference potentials was originally proposed by Ryaben'kii and can be
interpreted as a generalized discrete version of the method of Calderon's operators in the …

We review time-domain formulations of radiation boundary conditions for Maxwell's
equations, focusing on methods which can deliver arbitrary accuracy at acceptable …

We solve the wave equation with variable wave speed on nonconforming domains with
fourth order accuracy in both space and time. This is accomplished using an implicit finite …

When modeling wave propagation, truncation of the computational domain to a manageable
size requires nonreflecting boundaries. To construct such a boundary condition on one side …

We consider interior and exterior initial boundary value problems for the three-dimensional
wave (d'Alembert) equation. First, we reduce a given problem to an equivalent operator …
