How to read HENSTRUCT von Mises, displacement and safety factor
HENDOI · 2 November 2026
Plain-English guide to HENSTRUCT Results: max displacement, von Mises contours, screening safety factor, 2D vs 3D deform view, and what not to claim in review.
After Solve, HENSTRUCT Results show what the linear static engine returned. This guide teaches how to read those screens without treating them as certification FEA.
Read the method ID first
Every result carries a method ID (plate or panel). Quote it next to any stress number you put in a slide.
Displacement
Max displacement is the peak nodal motion under your BC and load. Enormous values usually mean the load magnitude or thickness is extreme for a first screen — not proof the solver “failed.”
Von Mises
Von Mises is a scalar stress intensity used for ductile yield screening. Toggle the contour field to von Mises, look for hotspots near clamps and load application, then ask whether Geometry (nx/ny) is fine enough to trust the hotspot shape.
Safety factor (screening)
When shown, safety factor compares stress intensity to the material preset yield. It is a screening ratio, not an airworthiness margin, not fatigue life, and not a bolt allowables check.
2D contour vs 3D deform view
3D deform extrudes thickness for visualization. The solve remains 2D plane-stress screening — not solid 3D certification FEA.
Reports
Build an R&D pack from Reports. Optional AI narrative uses engine data only. Keep honesty lines when you mail the pack.

Use this lesson in the HENDOI workspace
This page sits in How-to. HENFOIL, HENSYNTH, HENFLOW, HENSTRUCT and HENMESH share one account. These articles are screening lessons — not certification reports.
Featured · this article
HENSTRUCT
Plate and panel linear static screens with method IDs for early structural review — not general multiphysics FEA or certification analysis.
To Know MoreSection
HENFOIL
Turn this lesson into a section you can draw, check, analyse and compare. Run the polar at the Reynolds number of the vehicle. The method name stays on the result.
To Know MoreAircraft
HENSYNTH
After the section is chosen, set geometry and mission requirements, run screening, read compliance, synthesize candidates and download or mail the report.
To Know MoreCFD
HENFLOW
Labelled aerospace 2D CFD — panel, viscous, Euler and NS-SA — with method IDs on every Cp plot. Screening only, not certification CFD.
To Know MoreMesh prep
HENMESH
Structured airfoil C/O grids and section domain packs before HENFLOW or HENSTRUCT — prep with method IDs, not a general mesh tool.
