[gmx-users] constraints

[rams rams]

Dear Gromacs Users,

I have a problem in running the energy minimization of a protein along with
a substrate. In the .mdp file, if I use constraints =  all-bonds, the system
complains like the convergence is reached to system accuracy not to the one
I mentioned. If I replace the constraints = none, its running well. I would
like to know how serious it is to replace all-bonds constraints with none.
