The default dielectric constant is 1.0 which means a
vacuum environment. I tried change it to 80 when I run
my peptide in water box with periodic boundary. The
single peptide chain soon turned to totally unfolded
after 9 frames (4.5ps). Is it reasonable or I can't do
that?
Any suggestions on setting dielectric constant?
