pysimm: A python package for simulation of molecular systems

In this work, we present pysimm, a python package designed to facilitate structure generation, simulation, and modification of molecular systems. pysimm provides a collection of simulation tools and smooth integration with highly optimized third party software. ion layers enable a standardized methodology to assign various force field models to molecular systems and perform simple simulations. These features have allowed pysimm to aid the rapid development of new applications specifically in the area of amorphous polymer simulations.
