Diffraction Analysis
Overview
This skill provides guidance on hydrodynamic diffraction/radiation analysis using the available modules in digitalmodel. Three primary modules handle different aspects of the workflow:
| Module | Purpose | Primary Use Case |
|---|---|---|
| aqwa | Native AQWA analysis | Direct AQWA .LIS file processing |
| orcawave | OrcaWave diffraction | OrcaFlex-integrated analysis |
| bemrosetta | Format conversion | AQWA → OrcaFlex workflow, mesh conversion |
| diffraction | Unified schemas | Data structures and comparison framework |
