Open-source Python calculation platform for civil, mechanical, and electrical engineers.
What is CalcForge?
CalcForge is an open-source engineering software platform built for civil, mechanical, and electrical professional designers, academics, and students to build, use, and share free calculations. Originating from its parent company Civils.ai, the platform functions as an online beam calculator, free truss calculator, and comprehensive structural design hub. It allows users to write open source load calculation software using Python templates, rendering it a powerful tool for python programming for structural engineers. By offering accessible web tools like a calculator forge, it supports everything from complex finite element online free modeling to practical calculations like finding the cost of tunneling underground per meter or using a gradient calculator with working out.
