Parallel CFD method based on lattice Boltzmann method

The invention discloses a parallel CFD method based on the lattice Boltzmann method. The parallel CFD method based on the lattice Boltzmann method can conduct computation and analysis of hydromechanics in parallel for various complicated objects and is characterized in that a parallel distributed mesh generation method which is suitable for the lattice Boltzmann method is introduced, the time of mesh generation is greatly shortened, an algorithm which reduces the communication amount of the lattice Boltzmann method in the process of parallel iterative computation is established according to a distributed computer architecture, the iterative speed is improved, the expandability of the algorithm is improved, and the lattice Boltzmann method is made to be applicable to large-scale computation. A large number of numerical experiments show that the parallel computation method has good expandability and is more applicable to an ultra-large-scale computation system.
