Abstract: The asymmetric hexagonal mesh presented inthis paper has the merits of both rectangular meshand triangular elements (asymmetric polygonal mesh).It can, at the same time, eliminate the shortcomingsof them.To fully utilize the advantage of the asym-metric hexagonal mesh, a highly effective method,the tri-directional ueration method is dercloped,Theasymmetric hexagonal mesh in combination with thetri-directional iteration method gives a powerful toolfor numerical solution of partial differential equati-ons.
