This directory contains an input script for performing simulations with the srp/react pair style. The pair style srp/react interfaces fix bond/break and fix bond/create commands with the segmental repulsive potential. This is useful in simulating reactions with soft potentials such as DPD where minimizing topological violations is important. The input script in.srp_react is an example of a simulation of a degrading nanogel particle. An initial equilibrated structure of a nanogel particle (prior to degradation) is read from the restart file. The degradation reaction is simulated via the fix bond/break command. The simulation will generate the file bonds_broken.txt containing the number of bonds broken and fraction of bonds intact over the simulation time.
