PS model in Martini3 force field

[rswf]

Hello! I am working on a polymer simulation based on Martini3 force field. I noticed that there are Martini3 models for polystyrene in the polyply project. Comparison of the bonding parameters shows that the model is same with the Martini2 force field based model proposed in the literature (Coarse-graining polymers with the MARTINI force-field: polystyrene as a benchmark case). With the bonded parameters unchanged, the bead type becomes that in Martini3. May I ask if there is a reference to support such a change? Is the changed model validated?

@rswf you are correct. This approximation is okish but we have new updated parameters already. Hopefully, next week we can upload them to the library and make them available. A benchmark of the new parameters is avilbale here.

Thanks for your reply! This is indeed great news. And I think this paper is very meaningful for my research, thanks!
