Fields

_parent

Declaration
protected readonly APIBase _parent
Field Value
Type Description
APIBase

Properties

AxialAlignmentTolerance

The maximum distance the FE node can be from the expected axial position on the component it is connecting to for it to still be valid

Measurement: ShortLength

Declaration
public double AxialAlignmentTolerance { get; set; }
Property Value
Type Description
System.Double

CalculateAccelerationForceFromMassMatrix

Controls the calculation of the force due to gravity and the force due to any additional acceleration defined on the load case. Calculating the acceleration force from the mass matrix allows the orientation of the FE to be taken into account more accurately. If this option is not selected, then the defined force imported along with the stiffness and mass matrices is used and an attempt is made to correctly orientate this vector.

Declaration
public bool CalculateAccelerationForceFromMassMatrix { get; set; }
Property Value
Type Description
System.Boolean

CentreOfMassInLocalCoordinateSystem

Given in the local FE coordinate system and calculated from the mass matrix and node positions.

Declaration
public Vector3D CentreOfMassInLocalCoordinateSystem { get; }
Property Value
Type Description
Vector3D

FrequencyOfHighestMode

Measurement: Frequency

Declaration
public double FrequencyOfHighestMode { get; }
Property Value
Type Description
System.Double

GyroscopicMatrixIsKnown

The gyroscopic matrix is specified for this FE.

Declaration
public bool GyroscopicMatrixIsKnown { get; }
Property Value
Type Description
System.Boolean

IsGrounded

Calculates the frequencies (eigenvalues if the mass matrix is not known) of the FE and checks if the first six are zero. If so then the FE is not grounded, otherwise it is.

Declaration
public bool IsGrounded { get; }
Property Value
Type Description
System.Boolean

IsUsingFullFEModel

Declaration
public bool IsUsingFullFEModel { get; }
Property Value
Type Description
System.Boolean

Mass

Measurement: Mass

Declaration
public double Mass { get; }
Property Value
Type Description
System.Double

MassMatrixIsKnown

The mass matrix is specified for this FE.

Declaration
public bool MassMatrixIsKnown { get; }
Property Value
Type Description
System.Boolean

MassMatrixMNRadSKg

Declaration
public NodalMatrix MassMatrixMNRadSKg { get; }
Property Value
Type Description
NodalMatrix

NumberOfInternalModes

Declaration
public int NumberOfInternalModes { get; set; }
Property Value
Type Description
System.Int32

NumberOfPhysicalNodes

Declaration
public int NumberOfPhysicalNodes { get; set; }
Property Value
Type Description
System.Int32

RadialAlignmentTolerance

The maximum distance the FE node can be from the axis of the component it is connecting to for it to still be valid

Measurement: ShortLength

Declaration
public double RadialAlignmentTolerance { get; set; }
Property Value
Type Description
System.Double

ReasonScalarMassNotKnown

Declaration
public string ReasonScalarMassNotKnown { get; }
Property Value
Type Description
System.String

ReportNames

Declaration
public IReadOnlyList<string> ReportNames { get; }
Property Value
Type Description
System.Collections.Generic.IReadOnlyList<System.String>

StiffnessInFECoordinateSystemMNRad

Declaration
public NodalMatrix StiffnessInFECoordinateSystemMNRad { get; }
Property Value
Type Description
NodalMatrix

StiffnessMatrix

Declaration
public NodalMatrix StiffnessMatrix { get; }
Property Value
Type Description
NodalMatrix

ToleranceForZeroFrequencies

Frequencies below this value will be interpreted as zero for the purpose of checking if the FE is grounded.

Measurement: Frequency

Declaration
public double ToleranceForZeroFrequencies { get; set; }
Property Value
Type Description
System.Double
