# When to Use Each Module (+1)

## When to Use Each Module


| Scenario | Recommended Module | Reason |
|----------|-------------------|--------|
| Parse AQWA .LIS files | `aqwa` or `bemrosetta` | Native parsing, no external dependencies |
| Run OrcaWave analysis | `orcawave` | Direct OrcaFlex API integration |
| Convert AQWA → OrcaFlex | `bemrosetta` | Purpose-built converter with validation |
| Compare AQWA vs OrcaWave | `diffraction` | Unified schema comparison framework |
| Handle QTF data | `bemrosetta` | QTF parser and OrcaFlex export |
| Convert mesh formats | `bemrosetta` | GDF/DAT/STL conversion |
| Store/retrieve coefficients | `hydrodynamics` | Coefficient database |
