Dear Mark and Arthur, thank you for your reply. I did what you suggest me and almost everything worked. I created a topology with the two molecules without bonded parameters between them and put constrains on two of its atoms. I did a minimization and a simulation (md integrator). It worked perfect

Hi Mark, sorry, but could you be more specific whenyou say "Combine the topologies"? Was not it what I had done early? Thank you eef > The error you report is potentially of the everyday > http://wiki.gromacs.org/index.php/blowing_up variety. See > http://wiki.gromacs.org/index.php/Errors#1-4_inte

Hello Mark, thanks for your attention. I had already made some attempts setting the two molecules in the same block (as suggested in the forum) but I had no success. I tried to use restraints and constraints and but run always fails. Please I am sending my .mdp and .top files as well as the error
