How to use brownian dynamics with gromacs

GROMACS version:2021.4
GROMACS modification: No
I want to study the protein aggregation of two different protein, one is the monomer and another is a fibril having 5 chains. I want to use coarse-grained model. Is it possible to use brownian dynamics with gromacs?

Yes, you can set the integrator to bd in the mdp file for brownian dynamics (you can find more details on setting up the mdp parameters at https://manual.gromacs.org/documentation/2018/user-guide/mdp-options.html#run-control)

thank you, I got it
