lammps -in viscosity.in ``` 其中,viscosity.in是前面准备好的lammps输入文件。执行上述命令后,lammps将进行粘度计算,并输出最终的粘度结果。 通过上述案例,我们可以使用lammps软件计算液体的粘度。这个案例仅仅作为一个示例,具体的模拟系统和参数需要根据实际情况进行调整。同时,lammps还提供了丰富的功能和计算方式,可以...
以下是通过 GK 公式计算液体 Ar 的粘度的示例输入脚本: # Sample LAMMPS input script for viscosity of liquid Ar units real variable T equal 86.4956 variable V equal vol variable dt 38、 equal 4.0 variable p equal 400 # correlation length variable s equal 5 # sample interval variable d equal $...
fix 2 all viscosity 1000 z 1 1 # Run simulation ``` 完成LAMMPS输入文件后,我们可以使用以下命令运行模拟: ``` $ lammps < input.lmp ``` 模拟完成后,LAMMPS将生成输出文件,其中包含了模拟结果。我们可以使用以下命令从输出文件中提取出粘度数值: ``` $ grep "Viscosity of system" log.lammps ``` ...
So that you can see how to scale/unscale input and output values read/written by LAMMPS to verify you are performing the same simulation in different unit systems. The VISCOSITY directory has example scripts for computing the viscosity of a LJ liquid using 4 different methods. See the ...
