This version of Gromacs 3.0.2 has been extended to support local pressure. The simulation is considerably slower due to this (5-10 times), but you will be able to resolve pressure and surface tension as a profile along the Z axis. Check the README files in the source for details. This is more or less completely unsupported software :-) Uploaded 21:03 March 22, 2002 by Erik Lindahl (lindahl@gromacs.org)
