Re: [ESPResSo-users] Global Potential in Espresso

[Peter Kosovan]

Hi Lorenzo

You can use part command to set external force acting on particles which could 
simulate a uniform external field. This
should do for gravity, if your systems are not so huge that you would have to 
care about the curvature of the Earth.

If you need an arbitrary inhomogeneous external field, to my knowledge this is 
not implemented.
