Purpose
– 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.
Design/methodology/approach
– 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.
Findings
– CQ provides an efficient and accurate treatment of impedance boundary conditions.
Originality/value
– The paper suggests a new effective treatment of impedance boundary conditions.
