Hi all, I am performing a simulation of protein at air/water interface. For create an air-water interface I just expand the box in the z direction. So,aAfter minimization we can noticed that water molecules moved out of bulk water in the z direction. Why you just need to expand the z-axis for

So we just compute an interface vacuum-water like the picture in attach in increase the coordinate value of the z-axis of the box? BUt I don't understand how just like that we creat an empty place and water move to this place?? 2013/5/13 Justin Lemkul jalem...@vt.edu On 5/13/13 6:10 AM,

Dear Gromacs Specialists, I want to make a system consists of one box of solvent (for example water) that there is 100 surfactant molecules in it and water is in contact with air in surface as same as we do in laboratory in beaker. But I don't know how should I define this air-water interface

Hi, everyone   I find that i used T and P coupling in water-air interface, that is the reason my system imploded.   So i changed to NVT. But there are still fatal errors.   I have some questions concerning  .gro file.   for example in spc216.gro, there are both + and - psotions. But in other
