Area moments of inertia

This command allows to create different parameters from the Area moments of inertia calculation of a profile or a section. The center of inertia and the principal frame can also be created. This command creates an operation in the operations tree..

 

Creation stages / Use:

 

Click the icon or select the Analysis > Area moments of inertia... command from the drop-down menu.

 

  1. Select a face or a 2D sketch.

  2. Select the direction. The analysis is done regarding this direction.

  3. Check Center of inertia to use the center of inertia which is automatically calculated or select Point to select a point.

  4. Validate by clicking .

 

 

The direction must be parallel to the section or the sketch plane.

 

 

This command creates an operation which is listed in the operations tree.

 

 

Available Options:

 

 

Check the different parameters to create. The parameters are created in the Parameters folder of the entities tree. An Area Moments of Inertia sub-folder is created grouping all these parameters

Each validation of the command creates a new sub-folder. Each one can have different parameters (a different reference point, a different direction or section, ...)

 

 

If Center of inertia is checked in the parameter list, this point is created and listed in the Points folder of the entities tree.

 

 

If Principal frame is checked in the parameter list, this frame is created and listed in the Frames folder of the entities tree.

 

Modifications / Additional information:

 

Parameters can be removed directly from the Area moments of inertia folder. It is another way to do this instead of editing the command and unchecking parameters.

 

 

  • By editing parameters of the Area moments of inertia sub-folder, it is the command which is edited.

  • Parameters values depend on the geometry, the reference point and the direction. These values can't be manually changed.

 

 

  • Each Area moments of inertia sub-folder and/or parameter can be renamed. It is recommended to rename if there are several sub-folders.

  • The parameters unit can be changed one by one.

  • If you only want to know area moments of inertia values without creating an operation or parameters, use the Analyze area moments of inertia command.

 

 

List of created parameters:

Area 

Area of the selected section or sketch.

 

Center of inertia

The center of inertia is listed in the Points folder of the entities tree.

Principal frame

The principal frame is listed in the Frames folder of the entities tree.
