# Orcawave Aqwa Benchmark

## When to Use

- Validating OrcaWave results against AQWA benchmarks
- Comparing RAO amplitudes and phases between tools
- Verifying added mass and damping matrices
- Running automated benchmark test suites
- Generating comparison reports for quality assurance
- Establishing confidence in diffraction analysis results
- Identifying discrepancies between panel method implementations

## Python API

### Basic Comparison

```python
from digitalmodel.diffraction.comparison_framework import (
    DiffractionComparator,
    PeakRAOComparator
)
from digitalmodel.diffraction.aqwa_converter import AQWAConverter
from digitalmodel.diffraction.orcawave_converter import OrcaWaveConverter

# Load AQWA results
aqwa_converter = AQWAConverter()

*See sub-skills for full details.*
### Peak-Focused Validation

```python
from digitalmodel.diffraction.comparison_framework import PeakRAOComparator

# Peak-focused comparison (recommended for validation)
peak_comparator = PeakRAOComparator(
    aqwa_results=aqwa_results,
    orcawave_results=orcawave_results,
    peak_threshold=0.10,  # 10% of peak magnitude
    tolerance=0.05  # 5% tolerance
)

*See sub-skills for full details.*
### Matrix Comparison

```python
from digitalmodel.diffraction.comparison_framework import MatrixComparator

# Compare added mass matrices
matrix_comp = MatrixComparator()

# Compare at specific frequency
freq = 0.1  # rad/s
am_comparison = matrix_comp.compare_added_mass(
    aqwa_matrix=aqwa_results['added_mass'][freq],

*See sub-skills for full details.*
### Statistical Analysis

```python
from digitalmodel.diffraction.comparison_framework import StatisticalAnalyzer

# Initialize analyzer
analyzer = StatisticalAnalyzer()

# Compute correlation metrics
correlation = analyzer.compute_correlation(
    aqwa_raos=aqwa_results['raos'],
    orcawave_raos=orcawave_results['raos']

*See sub-skills for full details.*
