Plumed 2.0 is intended to give enhanced sampling capabilities to ESPResSo molecular dynamics engine.
It is still experimental, so use it at your own peril.
The documentation of Plumed 2.0 is on Github as well. It is regularly updated.
In order to compile it you should download the zip/tar.gz package up in this page.
After you compile Plumed 2.0 in the directory
/path/to/plumed2/ you can proceed to compile ESPResSo
On my machine it simply
$source /path/to/plumed2/sourceme.sh $export CPPFLAGS=" -I/path/to/plumed2/src/wrapper " $export LDFLAGS=" -L/path/to/plumed2/src/lib -lplumed " $./bootstrap.sh $./configure
plumed_testsdirectory. There you find some tests so you can understand how the input for plumed is parsed in.
I do not guarantee that this version will be kept syncronized with the ESPReSo version so you can try to merge yourself the plumed branch of this repo with the master of espresso git.
