Dear NAMD users,
I did perform a CG MD simulation with NAMD 2.7 within a membrane system. I have repeated my simulation with the new version of NAMD. There are same differences for the electrostatic energy values between two simulations. The electrostatic values increased -6000 to -60 kcal/mol. I used the command of improved Martini forcefield in the new version :
cosAngles on
martiniSwitching on
dielectric 15.0
PME off
Is this difference releated with the dielectric constant value?
Could anyone explain why this is happening? Am I doing something wrong?
Thanks
Sibel
