用LAMMPS模拟活性物质的分子动力学

Molecular Dynamics Simulations of Active Matter using LAMMPS

C. S. Dias

摘要:

LAMMPS是一个广泛流行的经典分子动力学软件包。它是为材料建模而设计的,但它为软物质的模拟做好了充分的准备。像LAMMPS这样的使用包有优点也有缺点。主要优点是优化的方法,主要是并行计算。主要缺点是,由于代码的复杂性,它有很长的学习曲线。这些笔记的一个目的是缩短研究人员开始使用LAMMPS来模拟软活性物质的曲线。在这些笔记中,我们首先讨论了LAMMPS中实现的一些分子动力学方法。我们向首次使用的用户提供了动手介绍,并以高级动手部分结束,在那里我们实现和测试主动布朗粒子模拟。

英文摘要:

LAMMPS is a widely popular classical Molecular Dynamics package. It was designed for materials modeling but it is well prepared for simulations in Soft Matter. The use packages like LAMMPS has advantages and disadvantages. The main advantage is the optimization of the methods, mainly for parallel computing. The main disadvantage is that, due to the complexity of the code, it ha long learning curve. One purpose of these notes is to shorten that curve for researchers are starting to use LAMMPS to simulate soft active matter. In these notes, we first discuss some Molecular Dynamics methods implemented in LAMMPS. We present an hands-on introduction to first-time users and we finish with an advanced hands-on section, where we implement and test Active Brownian particles simulations.
