A Hex-Mesh Generation Method Using Mean Value Coordinates
Authors: ,
Abstract: In order to find an applicable way of generating high-quality all-structured hexahedral meshes, a method of generating structured hexahedral mesh using mean value coordinates is proposed. Firstly, a new edge classification method and its execution condition are proposed which greatly cuts down limits for sub-mappable volumes by means of spreading local coordinate system. Secondly, virtual edges are created according to values of mean value coordinates in the computational domain and added into volume’s corresponding directed graph to eliminate inner loop vertices in the graph; therefore virtual volume decomposition process is avoided. Eventually, examples are given to illustrate the applicability of the proposed method. Meshing results manifest that the proposed method can stably generate high-quality hex-meshes and indicate potential application for hexahedral meshing of sub-mappable volumes.
