Hi all,
I was using AMBER16 (and 18 also) for simulating a protein, lipid water
system consisting of nearly 100,000 atoms. After energy minimization
(giving restraints individually on lipid, protein, water and then no
restraint minimization), I heated the system stepwise to 310K in NVT. But
when I changed to NPT and restarted the simulations, it shows very high
energy (very high temperature, sometimes in the range of 1000 K !!!) and
the simulation stops with an error message 'vlimit exceeds'. I tried to
continue in NVT, but the case is the same. What could be a possible
explanation? Can anybody suggest how can I avoid such overheating?
regards,
