Dear Lammps developers,
Here is a empty box, and I want to fill this box with a mono-disperse particle by gcmc operation. The "fix gcmc" command is as follows:
fix ID group-ID gcmc N X M type seed T mu displace keyword values
where M = average number of MC moves to attempt every N steps.
I remain other parameters constant, and only change the value of M from 10^0 to 10^9.
The particles can normally fully fill the box (about 1000 particles) when M is less than 10^4; but when M is larger than 10^5, the box can not be fully filled: many large empty space can be found by eyes, but the particle number as well as particle positions in the box basically remain the same (about 300 particles) even after a very long running time.
I have to used the final configuration (300 particles) to restart a gcmc simulation with a lower value of M (M=100), and the box is quickly fully filled.
Does M have a restriction range in gcmc process?
Thank you and best regards,
