The above figure shows part of the computed scattered near field from a 15 wavelength long model of an aero engine intake Introduction Over the last several years our group in the Computational Mechanics Section has been active in developing and applying computational methods for wave propagation. A particular area of concentration is the modelling of high frequency electromagnetic waves. This has involved generation of both frequency domain, and in particular time domain, integral equation codes. These employ smooth curvilinear isoparametric modelling, with typically 8 or 9 noded quadrilateral surface elements, and similarly smooth quadratic temporal modelling.
