Dear Justin and all GROMACS users, I'm simulating a monolayer system using the surface tension command in gromacs to set the surface tension and obtain the area( per molecule). Although my system is 2d and uniform : a slab of water covered with surfactant molecules and the surface tension reaches the desired value without problem, pxx and pyy are different and they don’t converge to a similar value. Is this an error or non physical problem? should I use a barostat with proper values for each direction instead of surface tension command to make pxx=pyy?
In conjunction with semiistropic pressure coupling, the x and y dimensions should have the same lateral pressure.
