Shell Local System
The Shell Local System subnode is used for interpreting directions of orthotropic and anisotropic material data and when stresses or strains are presented in a local system.
Coordinate System Selection
The Global coordinate system is selected by default. The Coordinate system list contains any additional coordinate system that the model includes. The coordinate system given is projected onto the shell surface as described in Local Coordinate Systems.
When a Shell or Plate interface is added, there is also a Shell Local System node added under Definitions. This coordinate can be used to reference the local directions selected in a Shell interface. It is used internally in the Shell interface, and can also be accessed from other physics interfaces. The coordinate system can also be used in a Coordinate System Surface plot to visualize the local directions.
•
Do not edit or duplicate the Shell Local System node added under Definitions.
•
If you add more than one Shell physics interface to the same component, one Shell Local System node is added under Definitions by each interface. Do not reference a coordinate system that belongs to another Shell interface.
