Remarks

This interface provides essential properties and methods for finite element body operations. It is designed to support fatigue analysis, material property evaluation, and finite element configuration.

Properties

AlphaX

Gets or sets the X-axis rotation factor for the FEBody.

double AlphaX { get; set; }

Property Value

double

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

This property defines the scaling factor applied to the X-axis rotation of the FEBody. It is used to adjust the rotational behavior of the FEBody during analysis.

AlphaY

Gets or sets the Y-axis rotation factor for the FEBody.

double AlphaY { get; set; }

Property Value

double

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

This property defines the scaling factor applied to the Y-axis rotation of the FEBody. It is used to adjust the rotational behavior of the FEBody during analysis.

AlphaZ

Gets or sets the Z-axis rotation factor for the FEBody.

double AlphaZ { get; set; }

Property Value

double

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

This property defines the scaling factor applied to the Z-axis rotation of the FEBody. It is used to adjust the rotational behavior of the FEBody during analysis.

AnalysisMethodEN

Gets or sets the analysis method used in the FEBody (Mean Stress Effect).

AnalysisMethodEN AnalysisMethodEN { get; set; }

Property Value

AnalysisMethodEN

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

Use to set the mean stress effect. This property specifies the method used for analysis in the FEBody. It determines how the fatigue analysis is performed. For more details, refer to the online manual section "Mean Stress Effect."

AnalysisType

Gets or sets the type of fatigue analysis.

FatigueAnalysisType AnalysisType { get; set; }

Property Value

FatigueAnalysisType

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

Use to set the method for fatigue life evaluation. This property defines whether the fatigue analysis is based on stress-life (SN) or strain-life (EN) methods. See "Fatigue Life Evaluation" in the online manual for more details.

The available values for are:

IsDeformationSuppressed

Gets or sets a value indicating whether deformation is suppressed for this body in analysis or visualization.

bool IsDeformationSuppressed { get; set; }

Property Value

bool

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

This property is typically used to control whether deformation effects are considered during post-processing or visualization. When set to true, the FEBody will be treated as rigid, and any deformation results will be ignored. This can be useful for simplifying analysis or focusing on other aspects of the simulation, such as rigid body motion.

Material

Gets or sets the material used in the FEBody.

IOperationMaterial Material { get; set; }

Property Value

IOperationMaterial

Examples

For an example that includes this property, see the Interface IOperationsFEBody.

Remarks

Use to set the material properties. This property provides access to the material characteristics associated with the FEBody, including physical and mechanical properties. Properly setting this value ensures accurate analysis and evaluation of the FEBody's behavior under various conditions.

double Scale { get; set; }

Property Value

double

Examples
