Enumeration Type Documentation

strong

Interpolation method for the excitation transfer function read from the HDF5 file.

Enumerator
CARTESIAN	Re/Im interpolation (default; avoids phase-wrap artefacts)
POLAR	magnitude/phase interpolation (matches legacy HydroChrono behavior)

strong

Wave excitation force calculation method.

Enumerator
AUTO	frequency-domain for regular and multi-heading irregular seas; IRF otherwise
IRF_CONVOLUTION	time-domain convolution with the excitation IRF
FREQUENCY_DOMAIN	frequency-domain superposition of the excitation transfer function

strong

Radiation damping calculation method.

Enumerator
RIRF_CONVOLUTION	direct convolution of RIRF kernels with velocity history (default)
STATE_SPACE	state-space approximation using exponential decay modes
