60 * @class SimInfo SimInfo.hpp "brains/SimInfo.hpp"
61 * @brief As one of the heavy weight class of OOPSE, SimInfo
62 * One of the major changes in SimInfo class is the data struct. It only maintains a list of molecules.
63 * And the Molecule class will maintain all of the concrete objects (atoms, bond, bend, torsions, rigid bodies,
64 * cutoff groups, constrains).
65 * Another major change is the index. No matter single version or parallel version, atoms and
66 * rigid bodies have both global index and local index. Local index is not important to molecule as well as
67 * cutoff group.
