A Novel Automatic Mesh Generation Technique for Curved Hexahedral

This paper presents a method for generating irregular curved hexahedral meshes from regular cuboid meshes. The algorithm utilizes cuboid to discretize the solid model, ignoring the inner and outer boundaries. Then, a special treatment process is applied to fit the boundary surfaces, generating high-quality irregular curved hexahedral discretized mesh. This algorithm is a novel raster method and is characterized by its simplicity, reliability, ease of programming, and high mesh quality.
