Due to the complexity of 3D geometry structure, regular gridding algorithms often generate a very large amount of mesh points which requires an enormous amount of computational power for later device and process simulations. A vector level control function and related generalized octree method is presented in this paper, and it allows mesh refinement in selected directions only. Thus the grid points can be placed more optimally and that enables efficient device and process simulations.
