3.3. Coordinate Systems
3.3.3. Solution Coordinate Systems
For homogeneous elements, element solution coordinate systems are generally identical to the nodal or the element coordinate systems adopted by the elements.
For composite elements, solution coordinate systems can be independently defined for different com-ponents, such as layers in a layered-shell element (SHELL181) and fibers in a discrete reinforcing element (REINF264). The solution coordinate systems in composite elements are also called layered coordinate systems, and are specifically identified via the RSYS,LSYS command.
For more information, see Rotating Results to a Different Coordinate System in the Basic Analysis Guide.
Following is a list of element types that support various material constitutive properties. To take advant-age of the many material properties available,use current-technology (rather than legacy) elements in your analysis.
Material models are specified via the TB,Lab command, where Lab represents the material model label (shortcut name). For more information about each material model, see the Material Reference.
For a list of material models and the elements that support them, see Material Model Element Support in the Material Reference.

Elements for stress analysis are used primarily in mechanical and civil engineering. Various categories of elements are available to meet the needs of many types of industries. The element categories can be identified by how the elements represent the geometry of the structures, the basic deformation and/or formulation assumptions, and the primary purpose of the elements.
