GROMACS version:2022.3  
MARTINI version:3.0.0  
I am currently performing calculations using martini3 force fields and would like to use polarizable water beads instead of the standard water beads that I use by default.  
I am thinking that there is only a force field that can be used with martini2, but has it already been developed?  
I found the above information based on the following URL:

Even if there might be some Martini experts on this forum, I think you will get better replies if you ask Martini specific questions on the Martini forum: [Index - Martini forum](http://cgmartini.nl/index.php/forum).
