liggghts通过.txt文件导入颗粒信息

 liggghts可以通过read_data命令读取颗粒信息和simulation box信息。比如:

read_data ./data/myspheres.txt

路径 ./data/ 中的 myspheres.txt 内容如下:

#10000个颗粒
10000
atoms             #颗粒的数量 1 atom types            #颗粒的类型 0.000000 0.054000 xlo xhi    #simulation box在x方向上的边界 0.000000 0.003000 ylo yhi    #simulation box在y方向上的边界 0.000000 0.150000 zlo zhi    #simulation box在z方向上的边界 Atoms #Atoms id Atoms type Atoms diameter  Atoms density  x_coordinate  y_coordinate  z_coordinate 1 1 0.00100000000000000 2250 0.00105000000000000 0.00225000000000000 0.00155000000000000 2 1 0.00100000000000000 2250 0.00160000000000000 0.00150000000000000 0.00155000000000000 3 1 0.00100000000000000 2250 0.00160000000000000 0.00225000000000000 0.00105000000000000 4 1 0.00100000000000000 2250 0.00210000000000000 0.00225000000000000 0.00155000000000000 5 1 0.00100000000000000 2250 0.00265000000000000 0.00150000000000000 0.00155000000000000 6 1 0.00100000000000000 2250 0.00265000000000000 0.00225000000000000 0.00105000000000000 7 1 0.00100000000000000 2250 0.00320000000000000 0.00225000000000000 0.00155000000000000 8 1 0.00100000000000000 2250 0.00370000000000000 0.00150000000000000 0.00155000000000000 9 1 0.00100000000000000 2250 0.00370000000000000 0.00225000000000000 0.00105000000000000 10 1 0.00100000000000000 2250 0.00425000000000000 0.00225000000000000 0.00155000000000000 11 1 0.00100000000000000 2250 0.00475000000000000 0.00150000000000000 0.00155000000000000 12 1 0.00100000000000000 2250 0.00475000000000000 0.00225000000000000 0.00105000000000000 13 1 0.00100000000000000 2250 0.00530000000000000 0.00225000000000000 0.00155000000000000 14 1 0.00100000000000000 2250 0.00580000000000000 0.00150000000000000 0.00155000000000000 15 1 0.00100000000000000 2250 0.00580000000000000 0.00225000000000000 0.00105000000000000 16 1 0.00100000000000000 2250 0.00635000050000000 0.00225000000000000 0.00155000000000000 . . . . 9999 1 0.00100000000000000 2250 0.0354499995000000 0.00225000000000000 0.0703500000000000 10000 1 0.00100000000000000 2250 0.0360000005000000 0.00225000000000000 0.0708500000000000
