Anisotropic pressure setting for curvature membrane

GROMACS version:2019.3
GROMACS modification: Yes/No
Hello, everyone!
I want to build a curvature lipid bilayers like the wave. And I also learn the anisotropic pressure coupling can make a curvature bilayer. But I don’t know how to set the pressure coupling parametes in mdp.
Does anyone know the setting or alternative methods to construct the curvature bilayer?
Thanks!
