COMPASS force field

Hi all,

I use COMPASS force field in Forcite.

There is a problem about bonding fromation, if I broke the C-C bond of ethane and the

distance between each carbon still equaled to the C-C bond length of ethane.

After relaxation, would they from bonding again?

if not, did i miss any setting?

Could I modify the cut-off distance  ?
