Thanks alot Goga N and Raman Preet Singh,

I have to simulate the polymer thin film of the order of sub nanometer
length scale, though I have gone through the DPDMacs, am able to run simple
DPD calculations, but haven't found any reference article that used
DPD-MACS. In addition to that we cannot simply calculate any thermodynamic
properties like Delta_G and Delta_H, using DPDMACS.  As Gromcs Approach of
free-enrgy calculation we cannot simply implement to It. I hope this would
topic of future interest those who want to develop.
However most of the references i have found either uses LAMMPS, DL_Meso and
Mesodyn. But post procssing needs to be coded on their own,I hope we should
go ahead with well tested LAMMPS.

Best
Praveen
