hello everbody

i am a research scholar and using material studio for my research in area of polymer nanocomposites. I am facing some problems like how to combine an epoxy resin with hardner so that perfect curing takes place. Is there any tool availabe for that in the software or it can only be sketched by hand?. How the ratio of both can be decided for curing.

Secondly what is the right way to select the exact ensamble for the dynamics run and relaxation after dynamics

Plese somebody help
