AutoTherm and AI

Not AI. Engineering you can sign your name to.

AutoTherm doesn't predict an answer. It solves the established equations, using properties from cited sources, the same way every time. You choose the method, enter what you know and judge the result, and you get through far more work. That's what makes an engineer harder to replace.

How generative AI tools and AutoTherm differ
Generative AI tools AutoTherm
How it answers Predicts a likely response from patterns in its training data
Solves the established equations of heat transfer, fluid mechanics and thermodynamics
Run it twice The answer can change
Same inputs, same result, every time
Where the numbers come from Not always shown
Every equation and property cited to an engineering text
Who makes the call It proposes, and you verify its reasoning and its numbers
You choose the tool and the inputs and judge the result. It handles the arithmetic and the lookups.

Better together. Use AI for what it does well: drafting, research, explaining a concept. For the numbers you put your name on, use a calculation.

Why AutoTherm exists

Big-company engineering tools, built for every engineer.

For decades I've built engineering software for industry. At TES International, we developed CFD and multiphysics software for the electronics industry, provided consulting, and built turnkey thermofluid toolsets for major aerospace and industrial companies. Those toolsets cut routine analysis from weeks to hours, but each one was a custom project, priced for a corporate budget and available only inside that company.

Everyone else made do with general-purpose software: programming environments where you still have to know the solution procedure, and math notebooks that don't know any engineering. Neither one is a thermofluid tool.

AutoTherm brings the turnkey approach to the individual engineer and the student: the reference material and the automated calculation together in one desktop application, for heat transfer, fluid mechanics and thermodynamics.

What's inside

Everything an engineer needs, in one place.

Each tool pairs the reference material with the automated calculation built on top of it — cited to its source, and ready to use.

See one tool, end to end: combustion

Enter a fuel and an air ratio. AutoTherm balances the reaction, pulls every property, returns the rate of heat transfer and iterates to the adiabatic flame temperature: the part that takes the longest by hand.

Referenced, not guessed

Every equation, property and correlation comes from established engineering texts, and each one is cited so you can check it.

Three disciplines, one growing toolset

Heat transfer, fluid mechanics and thermodynamics in one place, with new tools added regularly.

Learn the theory, too

Built-in resource topics define the concepts and equations behind the tools, so students can study the theory and check their answers in one place.

Runs on Windows

Installs on your own PC and is ready when you are. Mac users can run it through a Windows emulator.
