Hi
How to set up the pH value ?

what ions should I put in the solution?


The "pH" of your simulation is governed by the protonation state you assign to each of the titratable residues in your protein or other molecules of interest. There is no explicit representation of hydronium ions in the force fields available in Gromacs. Furthermore, the presence of hydronium would require acid-base chemistry (proton transfer) which is not possible under classical mechanics force fields.

But will be soon.
Maybe even in 4.1.

Thank you
