material studio

I am currently working on a  project based on Materials studio and facing certain problems regarding  energy minimisation of amorphous cell of double walled CNT(5%) and  LY-556(95%).

Its giving error regarding the forcefeild. And would also  want to know if there are some tutorials of material studio available..
