Our Excel spreadsheet software programs solve heat transfer, fluid flow, mixing, and many other problems that engineers often encounter.  We use them everyday in our consulting practice. You will love their features, user-interfaces, and open architecture.


Steve Hall started creating engineering software in 1979, shortly after he bought his first PC (an Apple ][+). He graduated from BASIC to VisiCalc, transitioned to SuperCalc and Lotus 1-2-3, and finally settled on Excel as his go-to software platform. He's a chemical engineer (BS ChE, University of Pennsylvania) with an MBA.
