Not supported yet
Defines a calculation which produces a Campbell diagram, showing how the system response frequencies change with the rotor's rotational speed.

Properties
MinimumCorrelationCoefficient: number, optionalcoming soon
The minimum acceptable correlation coefficient for the relationship between a state value and a state derivative. If it is below the minimum, the relationship is disregarded and a zero value is taken.
default = 0.8
Outputs: object(SteadyCalculationOutputs), optionalcoming soon
TransformRotorModesToNonRotating: boolean, optionalcoming soon
If true, a multi-blade coordinate (MBC) transform will be performed to transform the rotating modes into the stationary frame of reference. This will generate forward and backward whirling modes in a Campbell diagram.
default = False
AzimuthAngle: number (rad), optionalcoming soon
The fixed azimuth angle of the rotor (zero azimuth indicates blade 1 pointing upwards).
default = 0.0
MaximumPlotFrequency: number (rad/s), optionalcoming soon
The maximum frequency for modes to be shown in the Campbell diagram plot. The default value is 20 * 2 * 3.14159265358979323
default = 125.663706144
CustomLinearModelDll: object(CustomLinearModelDll), optionalcoming soon
The definition for an alternative calculation for the linear model analysis. If omitted, the Bladed calculation will be used.
Perturbations: object(BladeStabilityPerturbations), optionalcoming soon
The perturbations to apply during the linearisation calculations.
SteadyCalculationType: stringcoming soon
Defines the specific type of SteadyCalculation model in use. For a CampbellDiagram object, this must always be set to a value of CampbellDiagram.
ModeOfOperation: object (a type of CampbellDiagramModeOfOperation) coming soon
The operating mode of the turbine for which to produce a Campbell diagram.
Can be any of the following types:
