Hi Beniamino, If it's not a VMD Problem and you simulations crashes, I have also seen such problems, the solution is use smaller time step or use SETTLE/SHAKE to constrain the O-H bond in water. Rahul ___ gmx-users mailing listgmx-users@gromacs.org

This is a follow-up from my post in January regarding my attempts to reproduce some free energy of solvation calculations for modified cellulose oligomers. First, a question: I know that certain values of sc-alpha are preferred for different cases, but are there any values that definitely shoul
