Cross Section Types

The 12 cross section types, similar to those supported in the Ansys environment, provide a template of basic shapes to assist you in defining cross sections to be used in the model.

For each cross section type, Ansys DesignModeler computes the properties listed below and displays them in the Details View under Physical Properties. With the exception of the User Integrated cross section type:

  • You can promote the properties as read-only parameters.

  • You cannot modify any of the properties.

  • DesignModeler computes the properties based on the sketch you create.

Physical Properties of Cross Sections

  • A: Area of section, must be greater than zero.

  • Ixx: Moment of inertia about the x axis, must be greater than zero.

  • Ixy: Product of inertia.

  • Iyy: Moment of inertia about the y axis, must be greater than zero.

  • Iw: Warping constant.

  • J: Torsional constant, must be greater than zero.

  • CGx: X coordinate of centroid.

  • CGy: Y coordinate of centroid.

  • SHx: X coordinate of shear center.

  • SHy:Y coordinate of shear center.


Note:  DesignModeler treats a moment of inertia calculation as the area moment of inertia. Area density is calculated, not material density.
