* interactions (C++) and long range interactions (Fortran). If the |
| 60 |

* Fortran side is not set up before the force calculation, call |

* SimInfo's update function to settle it down. |
| 68 |

* (bonded) interactions and long range (non-bonded) interactions. |
| 70 |
|
* |
| 71 |
< |
* @note the reason we delay fortran side's setup is that some |
| 72 |
< |
* applications (Dump2XYZ etc.) may not need force calculation, so why |
