General Purpose Coarse-Grained Force Field 
Interested in supramolecular self-assembly ? Check out this review from our group, featuring many Martini-based simulations:
P.W.J.M. Frederix, I. Patmanidis, S.J. Marrink. Molecular simulations of self-assembling bio-inspired supramolecular systems and their connection to experiments. Chem. Soc. Review, in press, 2018. doi:10.1039/C8CS00040A
With a major new release of the Martini force field (Martini 3.0) imminent, it is also appropriate to perform an update on the inspiration for the force field: the Martini cocktail. We know the Classic Martini, Vodka Martini, Dirty Martini, Perfect Martini, Dry Martini and other, but after an evening of hard work we now have the official Martini 3.0 cocktail too! See here for a detailed decription how to mix it. Enjoy !
Interested to hear about the ins and outs of the Martini model ? Register for the forthcoming Martini webinar, April 18th !
Update: in case you missed it, you can find the recorded webinar on youtube
A nice example of how Martini can help you improving your performance, featuring the first Martini 3.0 dope:
