The Shell Local System subnode is used for interpreting directions of orthotropic and anisotropic material data as well as when stresses or strains are presented in a local system.
 
    The Global coordinate system is selected by default. The 
Coordinate system list contains any valid additional coordinate system that the model includes. If the selected coordinate system is not a boundary system, it is projected onto the shell surface as described in 
Local Coordinate Systems.
