PR

A Principal Stress/Strain plot displays values as vectors. These vectors can only be displayed on 2D and 3D elements (solids and shells).

This option will only be available if the current data component is either a principal stress or principal strain component.

By default PR plots are drawn as lines on a shaded element mesh, but "mixed-mode" plotting allows them to be superimposed on hidden or wireframe meshes too. See the PROPS box in Properties: Controlling colour, drawing style, transparency, lighting attributes and overlay of entities

Note that for solid elements principal stress/strain vectors are always shown averaged at the centre, even for solid elements with results at multiple integration points.
