How to cite

If CableDyn contributes to published work, cite the journal article that describes the formulation and its validation. To record the exact software version used, also cite the software release. Both entries are kept in the repository’s CITATION.cff, which GitHub exposes through its Cite this repository function.

Relation to the journal article

The journal article records the formulation as published; CableDyn continues to develop, and its defaults follow the methods the project currently recommends. The published methods remain selectable, so the article’s calculations can be reproduced. Differences from the article:

End tension channels. The article reports mooring fairlead and anchor tensions as the end element’s axial tension. FairTen and AnchTen report the end force, as defined in Output files and channels. That force adds axial damping and the end node’s share of weight, seabed contact, and drag at the actual velocity; the weight share is about half the end element’s submerged weight, which on a coarse mesh can reach several percent of a grounded chain’s anchor tension. This matches the end-force convention of MoorDyn and OrcaFlex. The distributed tension along a line keeps the article’s definition \(T = EA(\lVert\partial\mathbf r/\partial s\rVert - 1)\).
Finite-EI time integration. The article evaluates the internal force at the generalised-α blended configuration. By default, CableDyn blends the internal forces instead. This removes a time-step-dependent stretch bias on rapidly rotating cable tangents. Set False alpha_force_blend (see OPTIONS reference and defaults) to reproduce the article’s scheme.
Finite-EI static initialisation. By default, the static solution starts from a catenary and ramps up the bending stiffness in continuation, which is faster and more robust. On the article’s cables it reaches the same equilibrium to solver tolerance. Set sequenced cable_statics to run the article’s mesh-sequenced procedure first.

Every CableDyn result in the article, re-run in both configurations, is listed in validation/PAPER_REPRODUCTION.md.

Citing methods and reference data

CableDyn implements established methods — the cubic-Hermite Kirchhoff-rod element, Morison hydrodynamics, linear wave theory, and the generalised-α integrator — and is validated against published reference designs. When a study relies on a specific method or data set, cite the original source listed in References as well.
