HENDOI TECHNOLOGIES PRIVATE LIMITED designs and ships aerospace engineering software — not general CAD, not a multiphysics catch-all. One HENDOI account unlocks all five workspaces on one honesty standard.
HENFOIL owns the section. HENSYNTH owns the aircraft. HENMESH prepares the domain. HENFLOW screens the flow. HENSTRUCT screens the bay.
We stay explicit about limits. Screening supports early design. Wind tunnel, flight test and authority-approved methods still decide what flies.
Who it is for
OEMs, UAV teams, labs and bureaus.
Same engineering. Different meters.
02
UAV / eVTOL
Teams ranking sections, closing early mission questions and screening mesh / CFD / structure at the right fidelity.
03
Labs
Universities and research groups that need methods a student can teach and an advisor can audit.
04
Bureaus
Design offices that leave a selection trail someone else can defend in review.

Five aerospace natures.Labelled work. Honest depth.
Section → aircraft → mesh → CFD → structure. One HENDOI account. Method IDs on every calculated number — and a clear line between a solve and a visualization.
01
Section
HENFOIL
Own the section decision before the aircraft campaign.
Wing-section decision workspace — create, condition, analyse, compare, select and archive airfoils with labelled methods.
Solves. Stops tool-hopping and silent geometry failure so the section choice has a trail review can defend.

Aircraft
HENSYNTH
Close the mission early. Shape the aircraft. Trade with evidence.
Aircraft conceptual and preliminary design — mission requirements, multidisciplinary screening, compliance, synthesis, trades and reports.
Solves. Replaces scattered spreadsheets so “does this mission close?” is answered before expensive CFD or FEA.

Mesh
HENMESH
Defend the mesh before you burn a solver deck.
Aerospace simulation meshing preprocessor — CAD-aware 2D C/O grids, section domains and 3D wing extrude with quality gates before solvers.
Solves. Catches skew, y+ and wake-band failures at prep time — with airframe naming for HENFLOW and HENSTRUCT handoff.

CFD
HENFLOW
Answer the section aero question before a full-aircraft CFD campaign.
Aerospace CFD screening — CAD-aware setup, labelled 2D panel→viscous→Euler→NS-SA ladder, and extruded wing 3D RANS.
Solves. Gives aerospace section CFD with a method trail — without forcing days of general multiphysics deck craft.

Structure
HENSTRUCT
Screen the skin or bay before a full airframe deck.
Aerospace structural screening FEA — CAD shell prep, 2D plate and panel linear static solves, von Mises contours and 3D deform morph.
Solves. Answers early skin / spar / bay questions with labelled 2D FEA — without pretending it is certification solid FEA.

Pipeline
One climb — labelled at every step
HENFOIL chooses the section. HENSYNTH closes the mission. HENMESH prepares the domain. HENFLOW screens the flow. HENSTRUCT screens the bay.
API
Automate
Per-product keys — hfk_, hsk_, hfwk_, hstk_, hmk_.
Honesty
Faster early design,
because the tool
will not pretend.
01
Solve vs visualize
2D and 3D capabilities are labelled. A morph view or loft is not the same claim as a volume RANS or solid FEA solve.
02
Not certification CFD / FEA
Panel, VIC, NS-SA, ns-wing-3d, plate and panel screens support early decisions — not tunnel, flight-test or authority substantiation.
03
Honesty gates
ACCEPT / ACCEPT_WITH_WARNINGS / REJECT with method IDs on every calculated number so review sees the trail.
