of *course* NAMD will say that, unless you use a file with parameters set
up particularly for boron nitride.
the standard charmm parameter files are not set up for that. most likely,
you will have to look up publications that have done simulations of such
structures using charmm-like potential functions. not sure how well this
will work for you. many people i know use a manybody potential like
tersoff to model structures like that instead.
