A time‐domain approach for the simulation of elastic waves in heterogeneous soil domains is presented. It is based on modelling both near and far field by the scaled boundary finite element method (SBFEM). The SBFEM facilitates the use of a structured mesh in the near field region without the need to circumvent hanging nodes. The quadtree mesh is obtained automatically from image data. Radiation damping in the far field is modelled accurately by means of a displacement unit‐impulse‐response‐based formulation. An example analysis of wave radiation by an alluvial basin illustrates the potential of the proposed methodology. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
