Abstract

This paper proposes a benchmark to quantify frequency and amplitude variations caused by the spatial quantization of model geometry. A simple resonant cavity is modelled in 3 dimensions at a range of angles to the mesh axes. The quality measure resulting is compared with a classical analytical solution for such a cavity. Results from the Transmission Line Matrix method (TLM) are presented. The benchmark could be applied to most volume element based time domain techniques.
