Bare Hull

MaritimeThis functionality requires the Maritime add-on to be enabled. 5.4.0This functionality requires CAESES version 5.4.0 or later.

The Bare Hull is a component of the Ship Modeling Workflow and is accessible via the Maritime tab (MaritimeThis functionality requires the Maritime add-on to be enabled.) in the Model workspace. It is part of the modeling workflow for the ship type Hard Chine Boat. This component represents the bare hull itself, without any appendages or trimming surfaces.

Model Structure​

This model follows the same structure as the other models in the Ship Modeling Workflow. It is divided into three main scopes:

  • 01_geometryCurves: Contains all curves with physical meaning.
  • 02_surfaces: Contains all surfaces and functions used to generate meta-surfaces.
  • 03_brep: Contains the final BRep.

All design variables are located in the scope where they are first used. Their names are chosen to be descriptive of their functionality and the bounds are tested for robustness of the model. The Hard Chine Boat allows to change any values, object types or the overall model structure for maximum flexibility.

Inputs Taken from Hard Chine Boat​

The boat dimensions provided by the Hull Parameters component include:

  • Main Dimensions
    • LOA
    • Beam
    • Depth
    • Deadrise
  • Parameters
    • Design Draft (default value: depth * 0.5)

Geometry Curves​

Geometry Curves

For each Geometry Curve, the influencing Design Variables are defined within reasonable ranges to ensure meaningful geometries, as illustrated below.

Design Variables

Surfaces​

All surfaces are Ruled Surfaces generated from the Geometry Curves. No additional Design Variables are defined at the surface level. The generated surfaces are:

  • Bottom (two parts, shown in blue color)
  • Deck (green color)
  • Side (yellow color)
  • Transom (red color)

Surfaces

BRep​

The final bare hull BRep can be found in the 03_brep scope.
