Aero only

Not a general CAE vendor — a flight-sciences software firm

HENDOI TECHNOLOGIES PRIVATE LIMITED exists for aircraft, UAV/eVTOL, rotorcraft, and propulsion teams. If your decision is a wing, a rotor, a mission envelope, or a noise gate — that is our lane. Nothing else.

What we build

Three lanes. One standard: it has to be right

Solvers, geometry kernels, and HFOIL — each scoped for aeronautical decision-making, not retrofitted from another industry.

Custom aeronautical solvers

CFD, FEA, thermal, aeroelastic, propulsion, mission, and UAV/eVTOL solvers — scoped to your airframe programme, not a generic CAE template.

CAD kernels you own

2D and 3D geometry cores for aerospace apps that need BREP, NURBS, and sketch IP on your roadmap — not a rented black box.

HFOIL · HENMESH · HENFLOW · HENSTRUCT

Aeronautical CAD (HFOIL), aerospace mesh prep + HEN-AI (HENMESH), aerospace CFD + HENAI (HENFLOW), and aerospace structural FEA (HENSTRUCT) — domain-specific desktop products for flight programmes.

Why teams trust HENDOI

Credibility you can take into design review

  • Purely aeronautical

    We do not sell marine, civil, or general industrial CAE. Every product and service line is built for flight programmes — aircraft, UAV, rotorcraft, and propulsion.

  • Domain-first leadership

    Founded by an aeronautical engineer with years of hands-on solver development. Physics assumptions match how aero desks actually decide.

  • Validated before delivery

    Solvers ship against analytical cases, published data, or your reference set — with clear notes on what is proven versus still in development.

  • IP you can own

    Custom builds include ownership options so your flight programme is not trapped in a rented suite or a vendor roadmap.

Aeronautical services

Solvers for airframes, UAVs, and propulsion

Commission the fidelity your programme needs — CFD, structures, coupling, flight sciences, and more.

CFD Solvers

Custom aerodynamics solvers — inviscid, viscous, turbulence, compressible flow — for aircraft, UAV, and propulsion programmes worldwide.

Structural FEA Solvers

Airframe structural solvers — linear/nonlinear static, dynamics, modal, buckling, fatigue, and contact — for certification-minded aircraft programmes.

Thermal Solvers

Aerospace thermal solvers — steady/transient conduction, convection, radiation, and propulsion heat transfer — for airframe and systems thermal design.

Aero-Structural-Thermal Coupled Solvers

Coupled aero–structural–thermal solvers for aircraft and UAV programmes — FSI, thermal–structural, and heat-load interactions in one product stack.

Aeroelastic Solvers

Static aeroelasticity, flutter, divergence, control reversal, and gust-response solvers for aircraft, missiles, and high-aspect-ratio UAVs.

Flight Mechanics Solvers

Trim, stability, 6-DOF flight dynamics, and trajectory solvers for aircraft and UAV design offices and training academies.

HFOIL · HENMESH · HENFLOW · HENSTRUCT

Aeronautical CAD → aerospace mesh prep + HEN-AI → aerospace CFD + HENAI and/or aerospace structural FEA. Domain-specific — not general CAD, mesh, CFD, or industrial FEA suites.

HFOIL — Aerospace Aircraft Geometry CAD

Domain-specific 2D/3D CAD for complete aircraft geometry: mission templates, parametric airframe, wing/fuselage/tail/engine/gear builders, airfoil library, assembly, drawings, and STEP/IGES/STL export. Mesh prep lives in HENMESH; volume CFD in HENFLOW.

HENMESH — Aerospace Simulation Preprocessor

Native preprocessor for aircraft, UAV/eVTOL, rotorcraft, rocket/missile, and specialty aerospace cases: 16 Phase 6 workbenches, Phase 7 HEN-AI, industrial BL/HexCore/overset, quality gates, and suite export to HENFLOW.

HENFLOW — Aeronautical / Aerospace CFD

Native aerospace CFD desk: physics through hypersonic, specialised vehicle paths, flight manager, HENMESH suite import, post & PDF reports, validation, and thirteen HENAI CFD pillars — aeronautical programmes only.

HENSTRUCT — Aerospace Structural FEA

Native aerospace structural FEA desk: linear/nonlinear static, modal, harmonic, random vibration, buckling/post-buckling, composites, fatigue/fracture, thermo-structural, aeroelasticity/flutter/gust, rotor & landing-gear loads, margins, optimisation, and V&V — solver-only for flight programmes.
