VorLap

VorLap estimates aerodynamic loading and resonance risk for rotating structures by combining:

• Geometry-driven local flow orientation.
• FFT-based airfoil force spectra (CL, CD, CF, CM) across Reynolds number and angle of attack.
• Frequency overlap checks between shedding frequencies and structural natural frequencies.

What VorLap Produces

• Global force maps over inflow speed and azimuth.
• Global moment maps (computed as physical cross products, r × F).
• Node-level reconstructed time series for a selected operating point.
• Node-level reconstructed time series for time-varying inflow profiles (time, inflow_speed, inflow_direction_deg).
• QBlade fast-path conversion and export of external loading files (LOADINGFILE) for one-way structural forcing.
• Worst-case frequency mismatch metrics and detailed trace strings.

Verification and Testing

The automated test suite includes:

• Analytical tests for interpolation, rotation, reconstruction, and moment equations.
• File I/O validation tests.
• A single-blade verification case using repository reference data.

See tests/test_verification_case.py for the verification-based regression test.
