What the Airflow Around a Car Looks Like
October 2026
A CFD look at the air flowing over a car at speed, and how to read what the streamlines and the pressure field tell you about drag, downforce, and the wake.
How to Estimate FSAE Wing Downforce
October 2026
Downforce from a wing comes down to one formula. Here is how to work it out, where the lift coefficient comes from, and how to check it with a real simulation.
What Low Reynolds Number Does to Your Airfoil
October 2026
An airfoil that looks great in a textbook can disappoint on a real FSAE wing, drone, or rocket. Low Reynolds number is usually why, and here is what to do about it.
A CFD Starter Guide for Student Teams
October 2026
Your team does not need a supercomputer or a CFD class to get real value from simulation. You need a clear question, the right setup, and a fair comparison.
Is Cloud CFD as Accurate as Desktop CFD?
September 2026
Short answer, it can be, because the math is the same. Here is what actually decides CFD accuracy, and when a browser tool matches a desktop one.
Can You Upload Your Own CAD to an Online CFD Tool?
September 2026
Yes, you can test your own designs online without installing anything. Here is how CAD upload works, which file formats to use, and how to get a clean solve.
The Complete Beginner Guide to CFD Tunnel
July 2026
Everything you need to run your first aerodynamics simulation, from picking a shape to reading your drag numbers, plus how the plans and pricing work.
What Is a CFD Wind Tunnel?
July 2026
CFD stands for computational fluid dynamics. A CFD wind tunnel uses it to test how air flows around your design on a computer instead of in a physical tunnel. Here is what that means.
How to Run a Wind Tunnel Simulation Without Installing Anything
July 2026
You do not need heavy software or a workstation to test aerodynamics. Here is how to run a real CFD simulation right from your browser.
What Is a Virtual Wind Tunnel?
July 2026
A virtual wind tunnel shows you how air moves around your design without building a real tunnel. Here is what one is, how it works, and why most people should use one.
Why I Built a Wind Tunnel That Runs in Your Browser
July 2026
Real aerodynamics should not be locked behind expensive software and machines only big companies can afford. So I put it in a browser tab.
