[gmx-users] Cyclohexane simulation problem

2015-05-31 Thread mohsen shahlaei
Thank you Justin for prompt reply.I have been used coulombtype        = Cut-off in my mdp file for Cyclohexane energy minimization but the results sound odd.I used cyclohexane density (0.824 g/ml) for calculating number of CHX molecules in a 10 nm3 (about 56 molecules). Then I used following

Dear All, I am interested in simulation of cyclohexane box based on Lemkul tutorial. At first I built a box  using following commandgmx insert-molecules -ci chx.gro -nmol 500 -box 2.154434 2.154434 2.154434 -o chx_box.gro (I want a box with 10 nm3 volume)after run several times and convergence

[gmx-users] Simulation of Ethanol

Dear All,I am intending to simulate the pure ethanol box. I considered density of natural ethanol (789 kg / m3) and generate a box of pure ethanol using gmx genconf. after ending MD production, with NPT ensemble and P = 1 bar and T = 298, I have encountered a strange behavior, The average
