Well,
if the central bond in your system is ca-ne-nf-ca and you have specified a
ca-ne-nf-ca dihedral of 100000kcal/mole with correct phase and
multiplicity in a frcmod that you have sourced into leap before writing
the prmtop file and your initial system conformation is a cis-azobenzene
with reasonable geometry, then you should not get a trans-conformation
after minimizing.
Therefore, if you do get a trans-azobenzene, I guess one of the above
assumptions is not true. Which one that is is hard to tell without knowing
what exactly you did to set up your system.
