The success of field methods in computational fluid dynamics is dependent upon the quality of the computational mesh used to represent the physical domain. This report details the theoretical basis and method of use of a powerful multiblock grid generator. The approach allows complex three-dimensional domains to be rapidly meshed whilst giving significant control over the local quality of the grid. The program 'Fleximesh' produces a multiblock mesh of hexahedral cells for input to a range of flow solvers including those using unstructured data. Written in ANSI C it utilises flexible data structures and dynamic memory allocation to maximize the potential problem size.
