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

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  StatisticalAnalyzer


analyzer = StatisticalAnalyzer()


correlation = analyzer.compute_correlation(
    aqwa_raos=aqwa_results[],
    orcawave_raos=orcawave_results[]

*See sub-skills  full details.*
