Embodiment Construction
[0021] The moving particle method of the present invention parallelizes the equivalent particle load balancing acceleration method, and the specific steps are as follows:
[0022] Step 1: According to the initial distribution of particles in the calculation domain, generate the corresponding background grid. The background grid refers to the establishment of a regular background grid on the particle calculation area. Each background grid contains a certain number of particles. The grid points in the background grid do not participate in the actual calculation, and are only used for particle retrieval and area division. The shape of the background grid is square, and the side length of the background grid is equal to the particle radius. Count the particles in each background grid quantity;
[0023] Step 2: Use the equivalent particle equilibrium distribution method to divide the particle calculation domain. The equivalent particle equilibrium distribution method is to equivale...
