Dear all,
I have simulated a system consist of nanotube which it was filled by water inside( SPCE model), my question is:
I used rigid command for nanotube and I expect that nanotube’s atom don’t move , but it didn’t happen…my input is following. what can I do for fix this problem?
Thanks, for your attention,
