Although not technically considered failure, geometry checks are included to ensure that stiffened panels generated during sizing have dimensions that are reasonable in terms of fabrication, repair, and analysis. The rules are enforced by checking the relative proportions of the stiffener cross-section against user-defined criteria. The criteria are set in the Backdoor Data form. Three categories of geometric cross-section checks are included: geometric fabrication rules, geometric analysis rules, and geometric repair rules.
