The purpose of this paper is to propose an approach based on Convolution quadrature (CQ) for the modeling and the numerical treatment of impedance boundary condition.
The model is derived from a general setting. Its discretization is discussed in details by providing pseudo-codes and by performing their complexity analysis. The model is validated through several numerical experiments.
CQ provides an efficient and accurate treatment of impedance boundary conditions.
The paper suggests a new effective treatment of impedance boundary conditions.
