gmx can not minimize the sio2 because YOU did something wrong somewhere.
(topology, infiniteness of the system, box, solvent)

Program mdrun, VERSION 3.3.1

Source code file: nsgrid.c, line: 226



Range checking error:

Explanation: During neighborsearching, we assign each particle to a grid

based on its coordinates. If your system contains collisions or parameter

errors that give particles very high velocities you might end up with some

coordinates being +-Infinity or NaN (not-a-number). Obviously, we cannot

put these on a grid, so this is usually where we detect those errors.

Make sure your system is properly energy-minimized and that the potential

energy seems reasonable before trying again.



Variable ci has value -2147483648. It should have been within [ 0 .. 288 ]
