Dear All,
I am trying to pack a periodic cell, built using Mesostructure Template, with a single chain of polymer and solvent molecules at a DPD reduced number density of 3.Could someone help me with the steps?
Is there anyway to fix the number of polymer chains to be packed?When I add the polymer and solvent ,3-4 molecules of the polymer are packed  with the solvent molecules.I want to fix the number of polymer chain to 1.

Thanks for your time and consideration.
