摘要

However, the particle method does not introduce a computational grid; instead, particles placed in the computational domain are used as computational points. While the computational points of the grid method are fixed at the nodes of the grid, the computational points of the particle method often move through the computational domain. The process of the discretisation and solution of the governing partial differential equations are required in the particle method similar to that of the grid method.
