This paper proposes an algorithm for the generation and meshing of multi-scale composites 2D 3D unit cell model. The generation of unit cell model uses compact and reject algorithm, we use ellipse ellipsoid to represent its internal reinforcing particles. This algorithm could generate a large number of ellipses and high volume ratio of the unit cell with good randomness. When meshing, first we use adaptive line approximation algorithm that uses polygon to approximate the ellipse and polyhedron to approximate the ellipsoid. The Numerical experiments show that this algorithm generates high quality meshes in a very fast speed and the validity of the method.
