Hi Tsjerk, Thank you for this suggestion. It's a good idea to have previously equilibrated bricks then used for a main system. Unfortunately, my the ratios between ion and solvent usually appear quite far from the integer because I have fixed concentration. Moreover, a CNT is present in the same

Hi Vitaly, Do you have a rather fixed ratio between the two? ion:solvent = 1:10 e.g. Then you could make an arrangement of a single ion with surrounding solvent and replicate that with genconf. You could even do a short simulation setting rvdw to less than half the size of your small box :p for a

Hi, I want to create a system (conf.gro) consisting of a solvent and polyatomic (brachiated enough) ions. Using genconf and genbox I increase the number of molecules and then ions (or contrariwise). But genbox refuses to add all the requested particles at once (because of intersections, I guess).
