# Hydrodynamic Analysis

## When to Use This Skill

Use hydrodynamic analysis knowledge when:
- **RAO calculation** - Response Amplitude Operators for vessel motions
- **Added mass & damping** - Frequency-dependent hydrodynamic coefficients
- **Wave loading** - Diffraction, Froude-Krylov, radiation forces
- **BEM analysis** - Boundary Element Method for potential flow
- **Software integration** - WAMIT, AQWA, OrcaWave workflows
- **Frequency domain** - Linear wave theory analysis
- **Time domain** - Convolution for time-domain simulations
