itp 3. 随机插入一定摩尔浓度的urea到指定大小的盒子中(此处构建一个3*3*3 nm^3的立方体盒子) 插入分子数目和盒子大小以及浓度的关系如下: Nurea=cureaVNA 其中curea 为尿素的摩尔浓度(8 mol/L), V 为盒子的体积(27 nm^3), NA为阿伏伽德罗常数(6.022*10^23)。 计算得到nurea 是目标插入的尿素的分...

之后1 2原⼦距离会固定保持在0.153nm,即便1 2原⼦在[ bonds ]中定义是成键的也是如此。注意,.mdp⾥如果写constraint=none,只是说批量约束hbonds、all-bonds等没有了,在拓扑⽂件中⾃定义的constraint约束项仍然⽣效。顺便⼀提,在默认情况下,gromacs的⽔的结构是被settle算法约束住的,也就是所...
