[gmx-users] Re :minimization error

[Rongliang Wu]

Hello gmx-users,
           i have solved the minimization error myself but i found a wierd phenomenon.
           my original box was 4.463 4.463 3, i inserted 15 molecules and the densities was very low about 150g/l
, it was before adding solvent molecules, and it still could not do minimizations. i found there were molecules too close to each other, i enlarged the box but it didn't work. later, out of curiosity, i reduced the box size to 4 4 2 and interting the same 15 molecules, it worked! why? will it be more crowded if the box is too large? 
	

Thanks!

Regards!
