Hi Kawshik,

CHARGE provides current/charge analysis for semiconductor materials. Metals are only applied as contacts to apply voltage to the semiconductor. So, if a metallic object doesn't have an associated BC, then this will cause an error. If you can evaluate some of the effects that you are looking for without using the gold nanoparticles, then CHARGE will be useful. Otherwise, CHARGE won't be able to simulate it.
