if you simulate adsorption of your molecule at 2 bar and then seal the tube, then pressure inside tube will be 2 bar. in turn, you can control pressure outside using the barostat. though a difference between 1 bar and 2 bar in case of very spatially small MD systems and therefore huge pressure flu

I have this idea to try to "emulate" a chemical gradient, this is because i would like to see the diffusion of a molecule that it is caged in the SWCNT, an see if i can reproduce "a chemical gradient" in order to see a diffusion of the molecule, This idea is to try to model a chemical gradient co

Hi Dear Gromacs Users I was wondering if i want to simulate a SWCNT with water inside, it possible , to run an MD with the inside water with a diffent pressure (2 Bar) , and the outside water and CNT a 1 bar?, It is ok to use an index file, and use different pressure values with the barostat i thi
