* ForceManager is responsible for calculating the short range |
| 70 |
< |
* interactions (C++) and long range interactions (Fortran). If the |
| 60 |
< |
* Fortran side is not set up before the force calculation, call |
| 61 |
< |
* SimInfo's update function to settle it down. |
| 69 |
> |
* ForceManager is responsible for calculating both the short range |
| 70 |
> |
* (bonded) interactions and long range (non-bonded) interactions. |
| 71 |
|
* |
| 72 |
< |
* @note the reason we delay fortran side's setup is that some |
| 73 |
< |
* applications (Dump2XYZ etc.) may not need force calculation, so why |
| 74 |
< |
* bother? |
| 72 |
> |
* @note the reason we delay some of the setup is that |
| 73 |

* initialization must wait until after the force field has been |
| 74 |
