Sorption module for polymers

Hi..

I hv recently started using material studio for studying gas adsorption in polymers.

I followed the following steps:

1. Constructed the polymer using Build Polymer module of 25 repeat units

2. Carried out geometry optimization using Forcite module and Charges using QEQ

3. Constructed a amorphous cell of 4 polymeric chains.

4. Carried out optimization of the cell using Forcite module and Charges Using Current.

5. Lastly performed Sorption calculations.

Are these steps right? Or i hv made some mistake

Pls correct me with this
