Since the beginning of the seventies there is a growing interest in spectral methods as introduced by S.A. Orszag in 1970 [1]. Especially for problems with a high degree of continuity these methods can lead to very accurate results. In general problems are treated on simple geometries such as squares and boxes, either directly or by transformation of the region of interest.
