Convolution quadrature for the wave equation with impedance boundary conditions
We consider the numerical solution of the wave equation with impedance boundary conditions and start from a boundary integral formulation for its discretization. We develop the generalized convolution quadrature (gCQ) to solve the arising acoustic retarded potential integral equation for this impedance problem. For the special case of scattering from a spherical object, we derive representation...
متن کاملFast convolution quadrature based impedance boundary conditions
We consider an eddy current problem in time-domain relying on impedance boundary conditions on the surface of the conductor(s). We pursue its full discretization comprising (i) a finite element Galerkin discretization by means of lowest order edge elements in space, and (ii) temporal discretization based on Runge-Kutta convolution quadrature (CQ) for the resulting Volterra integral equation in ...
متن کاملFast convolution quadrature for the wave equation in three dimensions
This work addresses the numerical solution of time-domain boundary integral equations arising from acoustic and electromagnetic scattering in three dimensions. The semidiscretization of the time-domain boundary integral equations by Runge-Kutta convolution quadrature leads to a lower triangular Toeplitz system of size N . This system can be solved recursively in an almost linear time (O(N logN)...
متن کاملSparse Convolution Quadrature for Time Domain Boundary Integral Formulations of the Wave Equation
Many important physical applications are governed by the wave equation. The formulation as time domain boundary integral equations involves retarded potentials. For the numerical solution of this problem we employ the convolution quadrature method for the discretization in time and the Galerkin boundary element method for the space discretization. We introduce a simple a-priori cutoff strategy ...

Source-free wave-duct acoustics formulated as an initial value problem for the wave equation with impedance boundary conditions is considered. Properties of the corresponding C0-groups and their generators are given by emphasizing the spectral representation of these operators.
