OrcaWave (via OrcFxAPI)

Critical data extraction gotchas:

Property	Convention	Action Required
`.frequencies`	Returns Hz (NOT rad/s)	Multiply by `2 * pi`
`.frequencies`	Returns descending order	Sort ascending with `np.argsort()`
`.displacementRAOs`	Shape `(nheading, nfreq, 6)`	Transpose to `(nfreq, nheading, 6)`
`.displacementRAOs`	Rotational DOFs in rad/m	Convert to deg/m with `np.degrees()` for AQWA comparison
`.addedMass` / `.damping`	Same descending frequency order	Apply same sort index

See sub-skills for full details.

AQWA Standalone (Non-Workbench)

DAT file generation requirements:

Setting	Requirement	Consequence if Wrong
Element type	`QPPL DIFF` (not `QPPL`)	Zero RAOs — "NON-DIFFRACTING" elements
ILID card	`ILID AUTO <group>` after ZLWL	"REGLID: NO DIFFRACTING ELEMENTS FOUND"
SEAG card	2 parameters only: `SEAG (nx, ny)`	"FAILED TO READ SEA GRID PARAMETERS"
Line length	Max 80 columns	Delimiter read errors
Mesh quality	Panels ~square, facet radius check	FATAL error at 90° corners (non-overridable)
OPTIONS GOON	Continues past non-fatal errors	Does NOT override FATAL mesh quality
Heading range	-180 to +180 for no-symmetry bodies	Missing heading coverage

AQWA LIS File Parsing

Pattern	Gotcha	Fix
`ADDED MASS`	Double space between words	Use whitespace normalization
Damping frequency	WAVE FREQUENCY line is ~23 lines before DAMPING header	Search backward 30 lines
Matrix rows	Separated by blank lines	Skip blank lines in row parsing
RAO section	First occurrence = displacement RAOs	Skip subsequent velocity/acceleration sections
Heading expansion	5 input headings may produce 9 output (-180 to +180)	Filter to requested headings

BEMRosetta / Nemoh

Aspect	Status	Notes
BEMRosetta CLI	Mesh conversion only (`-mesh` mode)	Not a solver itself
Nemoh solver	Open source (GPL)	https://gitlab.com/lheea/Nemoh
Nemoh docs	Workshop tutorials	https://lheea.gitlab.io/Nemoh-Workshop/running-Nemoh.html
Integration	Future work	Nemoh backend adapter not yet implemented
