通过在同一算法下嵌入不同的粒子模型,即分子动力学模型（MD）和宏观拟颗粒模型（MaPPM）,成功地模拟了尺度和性质差别很大的两种物理现象—一两种分子间的相互扩散和流体的界面不稳定性.展示了采用粒子方法（PM）建立复杂物理系统离散模拟的通用并行算法和模块化软件的可能性,使该方法有希望成为与有限元（FE）和有限差分（FD）方法互为补充的主流模拟方法. By embedding different particle models under the same algorithm, namely the molecular dynamics model (MD) and the macro-particle model (MaPPM), two physical phenomena of very different scales and properties are successfully simulated - one or two intermolecular Interdiffusion, and interface instability of fluids. The possibility of using a particle-based approach (PM) to establish general parallel algorithms and modular software for the discrete simulation of complex physical systems is demonstrated, promising to be a finite element (FE) Differential (FD) methods complement each other’s mainstream simulation method.
