Discussion of results

To obtain section-cut forces for solid and link objects, the option to save section cuts must be selected under Moving Load Case Results Saved.

  • When saving section cuts for moving load analysis analysis is requested, then the section cuts (defined prior to the analysis as well as the section cuts defined or drawn after the analysis) yield the correct values.
  • When saving section cuts for moving load analysis analysis is NOT requested, section cuts for solid and link elements will produce zero results, but section cuts for frame and shell elements will produce correct results.
