[gmx-users] Error in mdrun

[Harshkumar Singh]

I have been doing simulation of 216 SPC molecules with cubic box dimension
3 nm.I have set the cut off at 1.2 nm but I get this error during mdrun

one of the box vectors has become shorter than twice the cut-off or
box_yy-|box_zy| or box_zz has become smaller than the cut-off error

The box vector is greater than double than twice the cut-off but I don't
seem to understand the other possible errors.How can I resolve them?
