ESPResSo is a molecular dynamics package designed for simulating and analyzing coarse-grained many-particle systems used in soft-matter research.
It supports research into polymers, liquid crystals, colloids, ferrofluids, DNA, lipid membranes, and other systems where groups of atoms or molecules are represented as beads. The software combines classical molecular dynamics with advanced algorithms for hydrodynamic and electrostatic interactions, and it’s controlled through Python scripting for flexible simulation workflows.
This is free and open source software.
Key Features
- Performs classical molecular dynamics simulations across multiple statistical ensembles.
- Supports coarse-grained bead-spring models for soft-matter and biological systems.
- Includes standard interaction potentials such as Lennard-Jones and Morse potentials.
- Provides advanced methods including lattice-Boltzmann hydrodynamics and electrostatic algorithms such as P3M, ELC, and MMM1D.
- Models rigid bodies using virtual site interactions.
- Handles rotationally non-invariant particles.
- Runs on desktop machines, clusters, and supercomputers using parallel execution.
- Offers Python-based scripting for custom and unconventional simulation protocols.
