# @scf

The scf section specifies the molecular geometry and molecular parameters.  
Below is a detailed explanation of the settings available in this section:   

| `conv_thresh` <a id="conv_thresh"></a> | |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Description** | Sets the convergence threshold for the SCF procedure. This defines the criterion for considering the SCF iteration to have converged, typically based on changes in energy or density. |
| **Type**        | float |
| **Default**     | 1.0E-8 |

| `restart` <a id="restart"></a> | |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| **Description** | Specifies whether the SCF calculation should restart from a checkpoint file, if available. This allows for the continuation of interrupted calculations or the reuse of previous results to accelerate convergence. |
| **Type**        | bool |
| **Default**     | True |
