(1) Begin
(2) Each processor updates the position of each particle in the Local_Store;
(3) If , go to (4); Otherwise, go to (5);
(4) Particle is sediment on the ground, ;
(5) If all particles in Local_Store are finished scanning, go to (6); Otherwise, go to (3);
(6) End
Algorithm 2: The sediment simulation algorithm of dust particles.
