Rotor Cross Section
In the Rotor Cross Section node, you specify the geometric properties of the rotor’s cross section. In addition, some stress evaluation properties can be defined.
Section Orientation
In this section, you specify the orientation of the principal axes of the section. Enter the Orientation vector defining local y direction in the matrix.
This is required input data.

Cross-Section Definition
Select a Section type — Circular, Pipe, or User defined. Then go to the relevant section below to continue defining the section. Select User defined if the rotor cross section does not match any of the predefined section types, or if the cross-section data is directly known. Each Section type also has a figure showing the section and its defining dimensions.
For equations and a figure see:
•
Circular Section
•
Pipe Section
Circular
Enter a value or expression for the Diameter do.
Pipe
Enter values or expressions for the following.
•
Outer diameter do
•
Inner diameter di
User defined
For User defined, go to User Defined, Stress Evaluation Properties, and Shear Flexibility to continue defining the cross section.
