Material orientation specifies the 0° 1-direction for each ply. Material direction is
set either by element or by property and is a rotation from the default solver
element system x direction. Specific definitions vary by user profile.HyperMesh supports common methods of material orientation for
each user profile. For example, the OptiStruct
convention is shown in the following image. Figure 1.
Material orientation can be set in the Composite Panel (2d > Composites > Material Orientation) or in the Aerospace Material Orientation Tab (Engineering Solutions > Aerospace User Profile > Aerospace > Composites > Material Orientation).
The composites panel is convenient for methods that involve vector projection or
system assignment. The Material Orientation tool should be used to assign an
orientation by curve.
