The most popular and widely used molecular dynamics (MD) software are include:
LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator): LAMMPS is a classical MD code focusing on materials modeling. It is open-source and freely available, and it can be used to simulate a wide range of systems, including nanoparticles. LAMMPS is known for its scalability and performance, making it a good choice for simulating large systems.
GROMACS (GRningen MAchine for Chemical Simulations): GROMACS is a general-purpose MD code that is widely used in the biomolecular simulation community. It is also open-source and freely available, and it can be used to simulate a wide range of systems, including nanoparticles. GROMACS is known for its user-friendly interface and its wide range of features.
NAMD (Not Another Molecular Dynamics): NAMD is a general-purpose MD code that is known for its scalability and performance. It is also open-source and freely available, and it can be used to simulate a wide range of systems, including nanoparticles. NAMD is a good choice for simulating large systems on parallel computers.
AMBER (Assisted Model Building and Energy Refinement): AMBER is a general-purpose MD code widely used in the biomolecular simulation community. It is not open source, but it is available for free to academic users. AMBER is known for its accuracy and its wide range of features. It is a good choice for simulating small systems with high accuracy.
