CFD add-in for Autodesk Inventor
Flow simulation inside Inventor. On your own PC. Your model stays there.
Pressure drop, Kv, flow split, drag and wind loads, on the part you already have. Laminaro takes you through six steps, solves on your own computer and gives every number with its ± and a report you can hand on.

Inside Inventor: the answer first, its ± and a plain verdict, and the flow in 3D next to it.
Meshing and solving happen on your PC, or on another PC in your office. Run as many as the job needs.
The ± from convergence, a plain verdict, and what to change when it isn't good enough yet.
Textbook results, measurements and EN 1991-1-4, with the less good cases published too.
What it does
The flow questions engineers actually get
Incompressible flow of air or water, inside a part and around it. Set up on the Inventor model, with the numbers a datasheet or a code check asks for.
Pressure drop and loss coefficient
Ducts, pipes, housings, manifolds: Δp from inlet to outlet and the loss coefficient K.
Kv and Cv for liquids
With a liquid, one inlet and one outlet, the valve-datasheet numbers sit next to the pressure drop.
Flow split
How the flow divides between outlets. Measure through any boundary or across any passage.
Drag, lift and Cd
Forces on a part in a free stream, the wake, and the pressure on every face.
Wind loads to EN 1991-1-4
Log-law wind over the ground, with the terrain's roughness and the basic wind velocity.
Fans
At an opening or inside the part, from the fan curve on the datasheet.
Parameter studies and flow sweeps
Give a named Inventor dimension three values and get the best one marked. Or run several flow rates and get the system curve.
Reports
PDF, Word or PowerPoint, with your pictures, the numbers and their ±, and how the study was set up.
Solved examples
Five real studies, with real numbers
Each one opens in Inventor already solved, with a short guided tour through the real windows.
Wind on a silo
A silo on open ground in log-law wind to EN 1991-1-4.

Water through a pipe bend
Ø50 mm, R 75 mm, water at 2 m/s. The valve-datasheet numbers.

Hot and cold water in a tee
Cold water meets a hot branch: how far downstream they mix.

Diameter study
Three diameters from one Inventor parameter, run and ranked.

Six steps on the LaminaroCFD tab
You take them in order, and each one gets a green tick when it's done. The CFD Tutor answers questions at any step.
Geometry
Say which body is the fluid, or let Laminaro build the air around your part.
Boundaries
Click a face and say what it is: inlet, outlet, wall or fan.
Fluid & flow
Air or water. The turbulence model is picked from the Reynolds number; you can change it.
Mesh
Draft, Standard or Fine, with the cell count and run time before you start.
Run
A Quick look first, then the real run, on this PC or another one.
Post-processing
Check, explore in 3D, measure, compare, and make the report.
How we check Laminaro
Compared with textbooks and measurements
Each capability is run against published results before it ships, by the same pipeline that runs your studies. The good cases and the less good ones are both on the list.
| Case | Reference | Deviation |
|---|---|---|
| Sudden pipe expansion | Borda–Carnot | −0.5 % |
| Cube in a free stream | Hoerner (1965) | +0.5 % |
| Silo on open ground | EN 1991-1-4 | +1.1 % |
| Pipe friction, Re 10⁶ | Colebrook (1939) | −2.0 % |
| Flat plate, face-on | Fail, Lawford & Eyre (1957) | +3.9 % |
| 90° bend, R/D 1.5 | Idelchik, K 0.17–0.21 | −7.6 % |
| Pipe friction, Re 10⁵ | Colebrook (1939) | −8.2 % |
