Simple and easy-to-use app for generating data file for LAMMPS MD simulator. Generate systems of any size containing linear, star, branch, pom-pom and cyclic bead-spring polymers. The polymers can be homopolymer, random, di-block or tri-block copolymers and may also contain explicit solvent. The branch and pom-pom can be block copolymers, with the backbone composed of one type and the side chains of another. The generated data file can be exported to iCloud/Google drive or shared via email.
