Abstract:Mapping method is widely applied by most of commercial mesh generators because of its efficiency, mesh quality, One of the obstacles to apply the mapping method and generate a graded all hexahedral mesh of high quality in an arbitrarily three-dimensional domain is the generation of hexahedral parent elements on a super-element that allows for gradations in three co-ordinate directions. This paper presents a pattern module's method to generate the graded mesh of all hexahedral elements in a cube and thus improves the mapping method. The method requires few calculations.
