Resumen de Efficient convolution based impedance boundary conditions

Alberto Paganini, María López Fernández

• 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.
