[gmx-users] Surface tension from gmx energy

[Own 12121325]

Dear Gromacs Users!

I am interesting how is possible to obtain the value for the surface
tension via the output from the gmx energy.

E.g. on the example I have two outputs where in the second case the ST were
introduced via the adding the negative lateral pressure along XY:


# 1)  no surface tension; 1 bar in XY
Energy                      Average   Err.Est.       RMSD  Tot-Drift
-------------------------------------------------------------------------------
#Surf*SurfTen               5.73271        4.2 <callto:5.73271%204.2>
  3314.05
-19.0927 <callto:3314.05%20-19.0927>  (bar nm)


# 2) -10 bar in xy

Energy                      Average   Err.Est.       RMSD  Tot-Drift
-------------------------------------------------------------------------------
#Surf*SurfTen               106.523        6.1 <callto:106.523%206.1>
   3072.3
-23.3618 <callto:3072.3%20-23.3618>  (bar nm)

How to convert these values of the averages to the dyn/cm ?

Thanks you!
