HENFLOW overview: aerospace-specific 2D CFD in the browser
HENDOI · 31 October 2026
HENFLOW is aerospace-specific CFD screening — panel, viscous, Euler and NS-SA — with method IDs, jobs and R&D reports. Not general multiphysics CFD. Not certification.
Aerospace CFD for the section first
HENFLOW is on HENDOI. It is the browser-based aerospace CFD workspace for labelled 2D section and airfoil screens: panel, viscous-inviscid coupling, Euler finite-volume and Navier–Stokes with Spalart–Allmaras. Every run returns a method ID. The UI shows what the engine returns — it does not invent coefficients or claim tunnel agreement.
This is aerospace screening CFD. It is not general industrial multiphysics software, not a substitute for a wind-tunnel campaign, and not an authority-approved certification showing. Treat every number as a decision aid for early aero questions, not as evidence for a type certificate.
Why aerospace-specific matters
General CFD suites can analyse almost anything. Aerospace teams often need something narrower: airfoil coordinates, Mach and Reynolds habits, Cp distributions, and a method label a reviewer can read. HENFLOW is built for that trail — next to HENFOIL section work and HENSYNTH aircraft screening on one HENDOI account.
What you run today
- Panel 2D — HF-PAN-2D-001 for fast inviscid screens.
- Viscous coupled — HF-VISC-2D-001 for integral boundary-layer coupling.
- Euler FVM 2D — HF-EUL-2D-001 for compressible section screens.
- NS-SA 2D — HF-NSSA-2D-001 for viscous aerospace screens.
The main path is labelled 2D section screening so early questions stay at the right fidelity. Optional extruded wing screening is available when selected — still screening, not full-aircraft CFD.
Plans — prices unchanged
HENFLOW shares Student USD 9, Professional USD 29 and Team USD 89 with HENFOIL and HENSYNTH. All solvers unlock on every paid plan; monthly meters (2D CFD runs, projects, compute credits) differ by plan. See the HENFLOW section on the pricing cards.
What we will not claim on day one
There is no public claim that HENFLOW matches a fixed tunnel database on every airfoil. Screening uses labelled aerospace methods appropriate to early design. Agreement with your own measurements is something you validate in your process — not something this announcement asserts.
How to start
Register or log in on HENDOI, open HENFLOW from the account dashboard, create a 2D case, set geometry and freestream, choose a method, and run. Keep the method ID with every Cp plot you share in review.

Featured · launch
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 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 MoreStructure
HENSTRUCT
Plate and panel linear static screens with method IDs for early structural review — not general multiphysics FEA or certification analysis.
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.
