This paper presents a full hexahedral mesh generation by plastering for three-dimensional geometries. In this method, hexahedral elements are generated inward by offsetting from initial boundary mesh. When the elements intersect with each other after offsetting, overlapped elements are improved by node relocation method. In order to construct conforming mesh, pyramid elements are added to all hexahedral elements on the meshing front. With this process unmeshed regions are covered with triangular elements and tetrahedral elements are then generated at unmeshed regions. Finally pyramid and tetrahedral elements are subdivided into hexahedral elements using the Geode algorithm. Sample meshes for several geometries are presented to demonstrate the effectiveness of the proposed algorithm.
