Chameleon, a generalized Monte Carlo software for the phase space analysis of complex, realistic polymer systems is presented. Chameleon implements the so‐called connectivity altering technique applied on polymer chains through Monte Carlo moves that do not mimic actual dynamics. These moves enable an accurate and fast sampling of configuration space and produce a robust environment for the prediction of the polymer's properties. Chameleon's capabilities are presented through a series of computations on well‐studied systems, namely polyethylene (PE), polystyrene (PS) and polyvinyl chloride (PVC) in the melt state. PE, PS and PVC are described via a united atom, coarse grained and all atom representation, respectively. The computed structural and volumetric properties of these systems are compared to experimental data and previous computational works, and found to be in excellent agreement. Finally, the shared memory parallel capabilities of Chameleon are presented and quantified in terms of speedup.

Chameleon:通用的连接更改软件,用于处理实际聚合物系统的特性

介绍了Chameleon,这是一种用于复杂,逼真的聚合物系统相空间分析的通用Monte Carlo软件。变色龙通过不模仿实际动力学的蒙特卡洛动作,实施了应用于聚合物链的所谓连通性改变技术。这些动作可以对配置空间进行准确,快速的采样,并为预测聚合物的性能提供了一个强大的环境。Chameleon的功能通过在经过充分研究的系统上进行的一系列计算来展示,这些系统分别是处于熔融状态的聚乙烯(PE),聚苯乙烯(PS)和聚氯乙烯(PVC)。PE,PS和PVC分别通过一个统一的原子,粗粒和所有原子表示进行描述。将这些系统的计算结构和体积特性与实验数据和先前的计算工作进行了比较,发现它们具有极好的一致性。最后,介绍了Chameleon的共享内存并行功能,并根据加速进行了量化。
