I need to simulate a large system of epoxy polymer using Lammps and Dreiding force field. I’ve built my model in Accelrys Materials Studio, however don’t know how to convert it to initial lammps data file. I’m familiar with msi2lmp, however I didn’t find dreiding.frc file for msi2lmp for my current job. I wonder if there is dreiding.frc file out there. please help me with this issue.
