| material Element | 
The orthotropyDirection is defined as rotation around the ribs z-axis. The rib coordinate system is defined as follows: x-axis is from leading to trailingeEdge of the componentSegment in the direction of the rib elongation. z-axis is normal to the rib in the direction of positive eta. y is defined by right hand rule. Rotation is around the z-axis. Zero degrees are at the x-axis positive direction.
