Dear All,
I am running MD simulation with TIP4P water and OPLS force field in NVT and
NVE. I have noticed a continuous energy increase in both NVE and NVT
simulations when i freeze a selected portion of my system. Recently i had
problem with temperature coupling, Berk has sent me a file which has solved
the problem of generating zero nrdf value. Now when i run the simulation
with two temperature coupling groups(one is for frozen and second one is for
non frozen) i have noticed the energy is continuously increasing. Even if i
don't use the temperature coupling similar observation was made. Can anybody
help me why it is happening?
Thanks in advance
Srinivas.
