Urey-Bradley parameters

Dear all,

I am in the process of setting up a simulation for a hyperbranched polymer,
and I am using CHARMM FF. During my searches I found a supplementary info
in a similar simulation that the author has considered Urey-Bradley
parameters equal to zero, while the original values in the CHARMM FF is not
zero. Could you tell me if it is reasonable to use a angle parameter from
CHARMM and then change its UB parameter to zero?

Truly yours,
