BDP thermostat on qbox-1.60.0
Posted: Tue Dec 16, 2014 10:13 pm
Hi Francois and all,
I'm reporting a problem I encounter with BDP thermostat on qbox version 1.60.0.
I ran a MD simulation of water (64 D2O molecules) at ??PBE ambient condition?? with BDP thermostat (th_temp = 400K, th_time = 5000 AU). Somewhat the simulation temperature dropped to at around 330K (not 400K) and stabilized there. I attach the input file (md.i), the temperature profile containing, <etotal>, <ekin_ion>, <econst>, <temp_ion>, (eng_H2O_64_BDP.dat) and <etotal_int> profile (e15.dat). At the first sight, the convergence seems to be ok but I might be overlooking something.
Let me know what I should check. Thanks!
Best,
Tadashi
