Beams and catenaries

Modeling of beams and catenaries was already possible but has now been simplified by the introduction of the beam element. Beams are structural members with weight and stiffness. Can be used to model anything between flexible beams, pipes and wire catenaries. Including mode-shapes and dynamics.

See: https://davedocs.online/DAVE-notebooks/beams.html (cantilever beams)

and https://davedocs.online/DAVE-notebooks/BeamCatenary.html (catenaries)

Export option to orcaflex

Exporting DAVE models to Orcaflex is now possible. However not all types of nodes are yet supported as some of them do not have a direct equivalent in orcaflex.

DAVE will export to an orcaflex .yml file. This means that the orcaflex API is not required for export.

What is supported are:

  • Vessels with 1st order wave forces, added mass, damping and linear hydrostatics.
  • Rigid bodies and axis systems including degrees of freedom using constraints.
  • Beams (orcaflex lines)
  • Cables (orcaflex winches)
  • Ballast systems (converted to 6D buoys)

Setup you model in DAVE including automatic vessel ballasting, goal seeks and first dynamic checks. Then export to orcaflex if in-depth numbercrunshing is required. It is possible to import the exported orcaflex model using the orcaflex API in the same python session.

Added options to convert shape based buoyancy to linear buoyancy properties.

  • Creation of carene tables: link
  • Conversion of shape-based buoyancy to linear springs: link


Exporting to orcaflex also enables cross validation of the DAVE static results:
