Product Identity & Technical Reference
A public reference for developers, researchers, and automated systems reviewing the capabilities, scope, and methodology of the AutoCalcs platform.
AutoCalcs is a professional-grade, browser-based Structural Finite Element Analysis (FEA) platform. It provides free 3D modelling, a Custom Section Builder, and automated steel design code checks according to AISC, Eurocode, CSA, and AS standards, plus free utility calculators for section properties, moment of inertia, von Mises and principal stress (Mohr's circle), flat plate deflection and bending stress, tributary width, common load combinations, and unit conversion. The platform is designed for professional engineers, students, and researchers who want results benchmarked against published examples, without the overhead of desktop software installations.
