As far as I understand you were going to implement the Charmm
polarization features into gromacs right? I have indeed chatted with
Alex a few times about this.
Tsjerk also mentioned being interested, but I don't know what he's planning.
We have implemented interactions between distributed charges (Gaussian,
Slater) - this can be ported straightaway to the master branch.
Polarization in the charge on a spring or drude or shell model has been
in gromacs since 1995, but there are still issues with slow convergence
of shell optimization. New solutions are appreciated - but not by just
upping the tolerance. Thole polarization for bonded terms is also
implemented but needs checking (start with the manual!). Feel free to
contact me on or off list.
