### Comments

- The order above reflects the contents of the OP2 file, but post-processors such as HyperView may display results in a different manner.
- For 2D elements, results are printed at the center of the element, followed by results at each grid when corner stresses are requested.
- For 3D elements, results are printed at the center of the element, followed by results at each grid when corner stresses are requested. In the OP2 format, regardless of the corner stress request, results are printed at each grid by duplicating results at the center.
