Hi Espresso users,
I used to use 0.005 for my timestep, but now due to lattice boltzmann, i should increase the timestep to 0.01.
The problem is that by increasing the timestep, I will get bond broken errors.
As I reviewed the mailing list archive this error happens when the system is not equilibrated enough, so I tried to make the warm up step and Setting P3M longer, but this error randomly occurs, I mean it sometimes occurs.
Does anybody know how to fix it?
Any help would be highly appreciated.
Best,
Roya
