Abstract
High quality mesh plays an important role for finite element methods in science computation and numerical simulation. Whether the mesh quality is good or not, to some extent, it determines the calculation results of the accuracy and efficiency. Different from classic Lloyd iteration algorithm which is convergent slowly, a novel accelerated scheme was presented, which consists of two core parts: mesh points replacement and local edges Delaunay swapping. By using it, almost all the equilateral triangular meshes can be generated based on centroidal Voronoi tessellation (CVT). Numerical tests show that it is significantly effective with time consuming decreasing by 40%. Compared with other two types of regular mesh generation methods, CVT mesh demonstrates that higher geometric average quality increases over 0.99.
