Dear Sir,

I am doing MD simulations using NPAT ensemble of homogenous lipid bilayer
During equilibriation, to apply constant pressure condition we applied
langevin piston dynamics

But instead of 1.013barr, we are always getting negative pressure values
and also, average pressure came out to be 0.

Could you please suggest me some way.

With Best Regards,
