Dear Gromacs users, I have a box 10 X 10 X 10 with 20 solute molecules in side it. I want to add a solvent of 25% X and 75% Y and so on to see the aggregation behavior of my molecules in different ratio of solvents X and Y. Can any body help me how to do this. The two solvent is mixed. e.g 25% X and 75% Y = desired Solvent Rob
