< |
* One of the major changes in SimInfo class is the data struct. It only maintains a list of molecules. |
| 80 |
< |
* And the Molecule class will maintain all of the concrete objects (atoms, bond, bend, torsions, rigid bodies, |
| 81 |
< |
* cutoff groups, constrains). |
| 82 |
< |
* Another major change is the index. No matter single version or parallel version, atoms and |
| 83 |
< |
* rigid bodies have both global index and local index. Local index is not important to molecule as well as |
| 84 |
