Under Principal Components, select a Type — Principal stress or Principal strain — to visualize either the principal stresses (the default) or the principal strains as vectors.

Under Principal values, enter information in the First, Second, and Third Value fields. The default are the three principal stresses (solid.sp1, solid.sp2, and solid.sp3, for example, for a Solid Mechanics interface; the prefix is the Name of the physics interface node), plotted using red, green, and blue arrows, respectively.

Under Principal directions, enter information in the table under First, Second, and Third for the X, Y, and Z coordinate fields. The defaults are the directions (eigenvectors) for the first, second, and third principal stress.

Under Positioning, select an Entry method: Number of points or Coordinates for the x grid points, y grid points, and z grid points. If Number of points is selected, enter the number of Points in each direction (the default is 7 for Principal Stress Volume plots and 15 for Principal Stress Surface plots). If Coordinates is selected, enter Coordinates (SI unit: m) or click the Range button (
