[gmx-users] Quesion about solvent simulation

[PeiQuan Chen]

Dear gmx-users：
   
   I have do another MD on a CH2Cl2 box that contain 216 molecules!Accroding the literature I have used the oplsaa force
field to do the simulaton, and fixed the molecules geometry(Cl-CH2-Cl 111.82;CH2-Cl 1.772) used the constraints(shake) algorithm as you do in the dmso and methol.The molecules geometry data and opls parameters for the CH2Cl2 is obtained in the JACS,1994,116,3494-3499. The simulational result is following: 

                MD        expt.
 Density:      1303 g/l        1325.5 g/l
 DHvap         27.4 KJ/mol      28.5  KJ/mol

Becasuse I am a freshman in this field, I don't know whether this result is good. Can anybody give me some hints. If the result is sound well, I will send the result to the www.gromacs.org.

Thank you in advance!



Sincerely yours
