** Error - OPTIMIZATION ABORTED -- GRADIENT OUT OF RANGE (EFP with water) **
Rahul Singh

Hello Friends,

I am facing one problem in completing the optimization of one geometry, which is dissolved in water. The molecule which I am studying has six conformers, of which three were successfully optimized. But I am having problem completing the simulation of the other three. Whatever I try, I always get the same error :OPTIMIZATION ABORTED.

-- GRADIENT OUT OF RANGE

-- MAXIMUM ALLOWED FORCE (FMAXT) = 10.000

This system has the concerned molecule, which is surrounded by around 400 water fragments. I have also attached one input with this mail. I will be greatly thankful if anybody can help me figure out the problem in the input file.

Please help me figure out the problem with this input file.
