Nodes#
Nodes are the building blocks of a scene.
In this chapter all standard nodes of DAVE will be introduced.
Building geometry and using joints#
The geometry of a model is constructed using Frames, Points, Circles and sometimes GeometricContacts
A beginners tutorial is available here
An overview of the geometry nodes is here
Cables, lines,catenaries#
The Cable node can be used to model flexible members without bending stiffness but with axial stiffness.
Cables can connect two or more points and or circles.
When a cable is given a mass, then it is modelled using the elastic catenary equation. Else it is just a line.
Friction can be added on intermediate connections
Cables can be used to model loops
Geometry of cables running over circular members (circles , roundbars) is fully supported.
Beams#
Axial members with bending stiffness and torsion can be modelled using the Beam node.
