Run a beam stress test and check it against theory
Claude drove the open-source FieldCraft modeler from one prompt to mesh and load a steel I-beam. The repo reports a tip bend of 0.176 mm versus 0.177 mm from beam theory.
Done with Claude
What they did
The FieldCraft team connected Claude to their free engineering simulation app through a connector that lets agents run its commands. With one prompt, Claude opened an I-beam and split it into small blocks for analysis. It then set the material, clamped one end, added a 1000 N load at the tip and solved. Finally it checked the bend against textbook beam theory.
How it went
The recorded session shows a tip bend of 0.176 mm. Beam theory gives 0.177 mm. The video is a real session with waits shortened.
Worth knowing
The app is early. Buckling and contact between parts are not built yet. The repo also lists 6 of 176 checked quantities as known failures.
Try it yourself with Claude
Using FieldCraft through its agent connector, open [part file]. Mesh it, then set the material to [material], clamp [face to fix] and apply [load in newtons] at [load location]. Solve the analysis and show me the stress and deformed shape. Then compare the key result, such as tip deflection, against a hand calculation from standard theory. Explain each step and flag any mismatch over [tolerance]%.
Swap the highlighted [parts] for your own details.
