* @brief As one of the heavy weight class of OOPSE, SimInfo |
52 |
> |
* One of the major changes in SimInfo class is the data struct. It only maintains a list of molecules. |
53 |
> |
* And the Molecule class will maintain all of the concrete objects (atoms, bond, bend, torsions, rigid bodies, |
54 |
> |
* cutoff groups, constrains). |
55 |
> |
* Another major change is the index. No matter single version or parallel version, atoms and |
56 |
> |
* rigid bodies have both global index and local index. Local index is not important to molecule as well as |
57 |
> |
* cutoff group. |
