[gmx-users] Gromacs Surface tension

[toma0052]

Hi,
     I am not sure if this is how I should ask questions regarding Gromacs,
but here goes.  I was wondering if anyone knows if there is an internal
program in Gromacs for calculating surface tension.  I would like to model
a lipid bilayer, and then determine the surface tension on that bilayer
under certain conditions.  Is there an included way for me to do that in
Gromacs, or do I need to modify the Gromacs code?

Thanks,
Mike
