## Abstract The steady three‐dimensional exterior flow of a viscoelastic non‐Newtonian fluid is approximated by reducing the corresponding nonlinear elliptic–hyperbolic system to a bounded domain. On the truncation surface with a large radius __R__, nonlinear, local second‐order artificial boundary

In this paper we revisit the problem of implementing wall boundary conditions for the Euler equations of gas dynamics in the context of unstructured meshes. Both (a) strong formulation, where the zero normal velocity on the wall is enforced explicitly and (b) weak formulation, where the zero normal
Asymptotic and exact local radiation boundary conditions (RBC) for the scalar time-dependent wave equation, ÿrst derived by Hagstrom and Hariharan, are reformulated as an auxiliary Cauchy problem for each radial harmonic on a spherical boundary. The reformulation is based on the hierarchy of local b
The time-dependent numerical boundary conditions for time-dependent magnetodydrodynamic fluid flow simulations have been studied. In this paper, the formulation of the time-dependent numerical boundary conditions are described in a systematic way such that they can be adapted to different applicatio
