Nodes overview

Nodes overview#

A short overview of all available node types is given here. You may skip this section if you want.

Backbone#

Type	Provides
`Axis`	An axis system with position and orientation and optionally a parent
`RigidBody`	An Axis with cog and weight

Geometry#

Type	Provides
`Point`	A 3d location
`Circle`	A circle with radius and orientation

Connectors#

Connectors connect two or more nodes and can apply a force on them based on their positions and orientations.

Type	Provides
`Cable`	A finite length cable with linear stiffness. A cable runs between two Point nodes and can run over multiple pois or circles. A cable may have a diameter.
`LinearBeam`	A beam connects two axis systems with a linear beam element
`LC6d`	Connects two axis systems with six linear springs. Orientation of the springs is determined by the main axis system
`Connector2d`	Connects two axis systems with two linear springs. Orientation of the springs is determined by shortest distance between the two axis systems

Forces#

Forces apply a force to a node. The magnitude of the force may depend on the position and/or orientation of the node.

Type	Provides
`Force`	An fixed force and/or moment applied on a Point
`HydSpring`	A linear hydrostatic spring attached to an Axis
`Buoyancy`	A buoyancy mesh (.obj or .stl) attached to an Axis
`Tank`	A (ballast)tank mesh (.obj or .stl) attached to an Axis
`BallastSystem`	A group of ballast-tanks for which a ballast-plan can be created

Contact#

Basic elastic contact can be modelled using meshes and contact-balls.

Type	Provides
`ContactBall`	A ball with a radius and a stiffness
`ContactMesh`	A mesh that can contact a contact ball

Information#

Type	Provides
`Visual`	(Almost) Everything gets better when visualized :-).
`WaveInteraction1`	1 st order hydrodynamic database

Groups#

Nodes or groups of nodes can be “managed” by another node. This makes it possible to standardize common groups of nodes. For example the nodes that make up a shackle or sling.

Type	Provides
`GeometricContact`	Bar-Bar or Pin-in-hole connections
`Sling`	A sling “splice” with eyes, mass, etc
`Shackle`	A standard shackle
