dear Mr.alizadeh thanks for your reply the repeatability of average pressure is my problem. average pressure isn't  repeatability when i repeat NPT simulation stage many times, simulation results are very different for the pressure average. my system is protein-ligand complex. How long do you

Dear Mahboobe, I do not know what exactly you mean. You know what, I do not know which your target system is. I mean when you want to simulate a system you should know which thermostat you need. Generally In mailing lists(as I always make some mistake) anyone knows any details of your system. I

Hi, I'm using tabulated potentials to create a hole in a membrane. I define three groups: 2 dummy-atoms, all hydrophobic lipid chains, and rest. For the interactions between the dummy atoms and the hydrophobic chains I define an exclusively repulsive potential. All other interactions are
