Coarse grained force field
WebJul 22, 2024 · Wang et al. [ACS Cent. Sci. 5, 755 (2024)] demonstrated that the existence of such a variational limit enables the use of a supervised machine learning framework to generate a coarse-grained force field, which can then be used for simulation in the coarse-grained space.

WebThe recent re-parametrization of the Martini coarse-grained force field, Martini 3, improved the accuracy of the model in predicting molecular packing and interactions in molecular dynamics simulations. Here, we describe how small molecules can be accurately parametrized within the Martini 3 framework and present a database of validated small ... WebThe Martini force field is a coarse-grained force field suited for molecular dynamics simulations of biomolecular systems. The force field has been parameterized in a systematic way, based on the reproduction of partitioning free energies between polar and apolar phases of a large number of chemical compounds.
WebDec 24, 2024 · Being coarse-grained, the Martini force-field enables simulations to be performed for larger systems and longer time-scales compared to corresponding atomistic simulations.
