Principal Components and Positioning
These sections are available for the Principal Stress Volume and Principal Stress Surface Plots:
Principal Components
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.
For transient problems, enter a Time.
Positioning
This section is not available for the 3D Principal Stress Surface plot.
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 () to define a range of values.
