Structural Engineering Calculation Software

Since 1982, we’ve built the structural engineering calculation software that’s helped tens of thousands of engineers. We’d like to help you too.

General Footing by FEM ENERCALC module


Our structural engineering calculation software is primarily used for discrete analysis and design of components for structures of low-to-mid-rise structures.

ENERCALC SEL includes 40+ structural calculation analysis and design modules. These modules are tools to analyze and design beams, columns, foundations, walls, earth-retention structures, 3D FEM, snow loads, wind loads, seismic requirements, and more.

You may know it as ENERCALC, the Structural Engineering Library, or SEL.

ENERCALC for Revit

ENERCALC for Revit

ENERCALC for Autodesk™ Revit™ simplifies structural design by bridging the gap between calculation & documentation.

It allows engineers to access the familiar power of ENERCALC SEL as a seamless real-time extension of your Revit environment.

ENERCALC’s use of the Revit API results in fast-paced, intuitive design with no import / export process.

What structural and civil engineers say


Almost moved to tears

I am almost moved to tears at finally finding this program and using it for the first time today. I tried various software last year and today finally found your software and it is absolutely the best I’ve ever experienced. Appreciate the help you give our industry and hope I can continue getting better with the software. Thank you so much for making my life easier!
