Amorphous cell containing graphene sheet with fucnctionalized MWCNT and LY556

hello all,

i am trying to form amorphous cell of amine functionalised dwcnt(6 chains of the group attached to cnt) and graphene sheet and LY556 polymer.

with the wt% as---3%cnt,    60.3% graphene(6*6 armchair)  and 36.7% LY-556 polymer.

the simulation is running from past 2 days and still no result is generated. i would appreciate soome help regarding this.
