Hi carlos,
isn't it possible that u make Kr=0 for all the bonds or few
bonds in my system. That way i indirectly drop the bond term wherever i need
without doing programming??
although i know programming, I need to know where all i need
to make the changes. How do i get those details?
thanx for ur cooperation
