PointInertia

https://bladednextgen.dnv.com/schema/0.4.1/Components/Tower/AddedInertia/PointInertia.json

An inertia added to a structural component.

  • AddedInertiaType: string = PointInertia
  • IgnoreGravityLoads: boolean
  • HeightUpTower: number (m)
  • SnapToNearestNode: boolean
  • Mass: number (kg)
  • Offset: object (Vector3D)
  • MomentOfInertiaTensor: array[number] (kgm²)
  • CompleteInertiaTensor: number

A type of AddedInertia

Properties

IgnoreGravityLoads: boolean, optional

If true, the loads due to gravity on this inertia will be ignored.

default = False

HeightUpTower: number (m), optional

The height measured from the bottom of the tower, assuming that the tower is mounted vertically.

default = 0

SnapToNearestNode: boolean, optional

If true, the inertias will be added to the nearest structural node, which may be at a significantly different height to that specified.

AddedInertiaType: string

Defines the specific type of AddedInertia model in use. For a PointInertia object, this must always be set to a value of PointInertia.

Mass: number (kg), optional

The mass to be added.

default = 0.0

Offset: object(Vector3D), optional

Centre of mass offset relative to the attachment node. This offset vector is defined using the local coordinate system of the attachment node.

default = {'X': 0, 'Y': 0, 'Z': 0}

MomentOfInertiaTensor: number (kgm²), optional

Moment of inertia tensor acting about the centre of mass. This tensor is defined using the local coordinate system of the attachment node.

default = [0, 0, 0]

CompleteInertiaTensor: number, optional

The symmetric inertia tensor acting about the attachment node. This tensor is defined using the local coordinate system of the attachment node.

default = 0
