Solution
ParticipantPlane strain (epsilon Z=zero) reaction can be interpreted as force/unit depth. Plane stress (SigmaZ=zero) uses PLANE183 elements with thickness (KEYO(1)=3). Reaction can be interpreted as force/unit depth times user defined thickness. By default user defined thickness is 1000mm in N-mm units, but can be changed by the user. Attached is a simple project file that illustrates a full 3D model and two 2D models (plane strain, plane stress) for comparison.
