6.3.9. Specifying Faces With Multiple Thicknesses and Layers

Thickness and Layered Section objects may be scoped to more than one face of a surface body. As a result, a face may have more than one thickness definition.

The order of precedence used to determine the thickness that will be used in the analysis is as follows:

  1. Imported Plies objects

  2. Imported Thickness objects

  3. Layered Section objects

  4. Thickness objects

  5. Thickness as a property of a body/part

For multiple objects of the same type, the object lower in the tree (more recently created) will be used in the analysis.

This thickness may not be the desired thickness to be used in the analysis. In a large model, you may want to fix this problem prior to solving the model.

You can search for faces with multiple thicknesses by selecting Search Faces with Multiple Thicknesses from the context menu of any of the following: the Geometry folder, a Body object (individual or group of objects), a Thickness object or a Layered Section object. For each face found with multiple thicknesses, a warning message similar to the one shown below will be displayed in the message box.

This face has more than one thickness defined. You may graphically select the face via RMB on this warning in the Messages window.

To find the face and its corresponding thickness objects for a particular message, highlight that message in the message pane, right-click the message and choose Go To Face With Multiple Thicknesses from the context menu. The face associated with this message is highlighted in the Geometry window and the corresponding thickness objects are highlighted in the tree.

If there is no face with multiple definitions, the following information will be displayed in the message box.

No faces with multiple thicknesses have been found.

A related Go To option is also available. If you highlight one or more faces with thickness definition of a surface body, then right-click in the Geometry window and choose Go To > Thicknesses for Selected Faces, the corresponding thickness objects will be highlighted in the tree.


Note:  You cannot search for Imported Plies that overlap with other thickness objects. However a warning will be generated during the solution if this situation might exist.
