HENSTRUCT

Aerospace-specific structural FEA — strength, dynamics, composites, flutter — not general CAE.

HENSTRUCT is Hendoi’s structural desk for aeronautical and aerospace programmes: linear through nonlinear static, modal and vibration paths, buckling, composites, fatigue, thermo-structural coupling, aeroelasticity/flutter/gust, margins, and V&V. Geometry from HFOIL; meshes from HENMESH; aero loads optionally from HENFLOW.

Contact / licensingAll products

Keep structural analysis inside the aerospace domain. HENSTRUCT specialises in flight programmes so load cases, composites, flutter, and margins speak MoS and FAR/CS language — not generic CAE menus.

What you can do in HENSTRUCT

Aerospace structural FEA — not general CAE

HENSTRUCT is scoped to aeronautical and aerospace programmes: airframes, UAV/eVTOL structures, composites, aeroelastic coupling, rotor and landing-gear events. Not automotive crash, civil structures, or general mechanical CAE.

Full aerospace FEA platform shell

Project manager, materials, aerospace load cases, solver families from linear static through flutter, post-processing, margins of safety, PDF reports, optimisation, validation benchmarks, and HPC foundations — organised as a structures desk.

HFOIL → HENMESH → HENSTRUCT chain

Prepare geometry in HFOIL (CAD), mesh and quality-gate structural volumes in HENMESH, then solve strength, dynamics, and margins in HENSTRUCT. Couple pressure loads from HENFLOW when aeroelasticity or gust needs them.

Twenty-five aerospace solver capabilities

Linear/nonlinear static, modal, harmonic FRF, random vibration, response spectrum, transient, buckling/Riks, composites, fatigue/fracture, thermo-structural, aeroelastic/flutter/gust, rotor, landing gear, joints, MoS, load cases, optimisation, V&V, and HPC.

Certification-minded margins & load cases

Named thrust/fuel/payload combinations, FAR/CS-style factors, UnifyMargins API, and review-ready MoS outputs so strength decisions survive design reviews.

Solver-only — CAD and mesh stay upstream

HENSTRUCT does not replace HFOIL or HENMESH. It owns the structural solve, post, margins, and reports once the mesh and materials story is ready.

Solver families & aerospace paths

Organised for flight structures — with Production / Foundation / Roadmap maturity called out in the desktop capability map.

1–4. Static, nonlinear, modal & harmonic

  • Linear static — displacement, stress, strain, reactions, SF, energy balance + residual checks
  • Nonlinear — geometric NL, J2 plasticity, contact + Coulomb friction
  • Modal — frequencies, shapes, participation, effective mass, eigen residual
  • Harmonic — direct + modal complex FRF (Re/Im) with stress amplitude

5–8. Dynamics, buckling & composites

  • Random vibration — modal CQC/SRSS + Miles / GEVS PSD → RMS
  • Response spectrum — pyroshock SRS tables with CQC/SRSS
  • Transient — Newmark + modal transient with energy checks
  • Buckling + spherical Riks post-buckling past λ_cr
  • Composites — CLT ABD, Tsai–Hill/Wu, Hashin, Max Stress/Strain

9–16. Fatigue, thermal & aeroelasticity

  • Fatigue — Goodman/Basquin + ASTM E1049 rainflow Miner + LCF
  • Fracture — Paris DT + near-tip K proxy
  • Thermal stress and thermo-structural (heat → expansion → stress)
  • Static aeroelastic FEA — iterated twist→lift redistribution
  • Flutter — typical-section + modal flutter with Ka/Ca aero matrices
  • Gust — Pratt V–n + 1-cosine dynamic gust transient

17–25. Rotor, gear, MoS, opt, V&V, HPC

  • Rotor centrifugal + rotating-frame geometric stiffness
  • Landing-gear oleo spring–damper drop energy peak load
  • Joints — Huth + bonded MS + FEA spring connectors
  • Failure / MoS — FAR/CS factors + UnifyMargins API
  • Aerospace load cases — thrust/fuel/payload + combo suite
  • Optimisation — size/topology + Genetic / PSO paths
  • V&V benchmarks + OpenMP assembly / HPC foundations

Typical workflow

Mesh → loads → solve → margins

01

Import structural mesh

Bring a quality-gated structural mesh from HENMESH (or an approved FEM bridge). Confirm units, element types, and material regions.

02

Assign materials & properties

Metals, composites (CLT stacks), connectors, and temperature-dependent properties for thermo-structural cases.

03

Book aerospace load cases

Named manoeuvre, gust, thrust, fuel, and payload combinations — with FAR/CS-style factors where your programme requires them.

04

Solve

Dispatch linear/nonlinear static, modal, harmonic, buckling, aeroelastic, or specialty paths. Monitor residuals and energy checks.

05

Post, margins & report

Inspect stress/strain/modes; run UnifyMargins; export PDF strength packages for design review.

06

Optimise or validate (optional)

Size/topology or GA/PSO paths under hard constraints; run V&V benchmarks before trusting production MoS.

Who it serves

Teams that run aerospace structural campaigns

  • Aircraft and UAV structures desks that want aerospace-only FEA workflows
  • eVTOL / airframe strength teams handing off from HENMESH prep
  • Composites, fatigue, and aeroelastic analysis groups
  • University labs teaching aerospace structural analysis with a clear product chain

HENSTRUCT is Hendoi’s native desktop structural FEA workbench for aeronautical and aerospace programmes: strength, dynamics, buckling, composites, fatigue, thermo-structural coupling, aeroelasticity, margins, and validation — not a general industrial FEA suite.

Frequently asked questions

Straight answers about aerospace-only FEA scope, CAD/mesh handoff, margins, and licensing.

What is HENSTRUCT?

HENSTRUCT is Hendoi’s native desktop structural FEA product for aeronautical and aerospace analysis only — linear through nonlinear static, dynamics, buckling, composites, fatigue/fracture, thermo-structural, aeroelasticity/flutter/gust, margins, optimisation, validation, and HPC foundations.

Is HENSTRUCT a general FEA suite?

No. It deliberately focuses on aerospace structures so load cases, margins, composites, flutter, and gust speak flight-programme language — not generic mechanical CAE menus.

Does HENSTRUCT include CAD or meshing?

No. It is solver-only. Prepare geometry in HFOIL and structural meshes in HENMESH, then solve and report in HENSTRUCT.

How does HENSTRUCT connect to HFOIL, HENMESH, and HENFLOW?

Typical chain: geometry in HFOIL → structural mesh in HENMESH → solve in HENSTRUCT. When aeroelastic or gust cases need pressure fields, couple loads from HENFLOW CFD campaigns.

What platform does HENSTRUCT run on?

Native desktop builds for Windows, Linux, and macOS (C++ / HendoiUI). Commercial, lab, and academy licensing is available worldwide via Contact.

What maturity should I expect?

Core static, modal, buckling, composites, fatigue, margins, and load-case paths are productised for aerospace desks. Specialty flutter, HPC MPI, and some optimisation paths carry foundation/roadmap maturity — ask for the current capability map on a demo call.
