The local stress tensors allow you to choose which result to plot in the graph. Six local stress tensors are available:

Click one of the six buttons to display that local stress tensor in the graph area.
For example, NN is the normal stress in the local N direction and TH is the shear stress along the HN plane in the H direction. Be sure to specify the First Point, Last Point, and Reference Point to define the Stress Classification Line (SCL) and the local coordinate system before reviewing results from the graph.
