H5MD : HDF5 for molecular data ============================== [H5MD] is a file format specification, based upon [HDF5], aimed at the efficient and portable storage of molecular data (e.g. simulation trajectories, molecular structures, …). H5MD implements data models for a variety of computational problems, e.g., molecular simulation using molecular dynamics, or computational fluid dynamics using multi-particle collision dynamics. The first release of the specification, H5MD 1.0.0, describes the storage of particle trajectories (positions, velocities, forces and species) as well as thermodynamical observables. Future extensions will be considered on the basis of discussion with users of H5MD. The development of H5MD was started by Pierre de Buyl, Peter Colberg and Felix Höfling. H5MD now includes contributions by other developers. H5MD is available under the [GNU General Public License] version 3, or any later version. H5MD is presented in P. de Buyl, P. H. Colberg and F.
