SPICA: Surface Property fItting Coarse grAined model


SPICA Force Field

The SPICA is an empirical coarse-grained (CG) force field that is designed to reproduce thermodynamic quantities, such as surface/interfacial tension and density, as well as distribution functions obtained from all-atom molecular simulations based on the CHARMM force field. The SPICA force field adopts the CG model library of so-called SDK (Shinoda-DeVane-Klein) CG force field, but includes a larger molecular library with the improved quality of CG parameters. This page provides the updated force field data (topology and parameter), molecular dynamics (MD) simulation protocols and useful computational tools to simulate biological or soft material systems using the SPICA force field.
