Hi,
I want to simulate a water droplet on a rigid surface at a specific temperature (300 K in this case), and I was wondering how to simulate a surface with imobilized atoms at a specific temperature because I read some papers in which the effect of a rigid surface temperature was investigated.
I tried to use the “fix spring/self” command for the surface atoms and the nvt ensemble for both water and the surface atoms, but it didn’t work because the surface atoms moved, so it destroyed the order of the surface crystal structure.
I would appreciate it if anyone could assist me.
