Hi everyone,
I wanted to share an online structural analysis tool I built (lightweight 3D FEA): autocalcs.com
Can try it without even needing to signup (20 node limit). Runs 100% in your browser using the open-source PyNite solver, so it performs: Linear static, P-Delta, Tension/compression-only
Would love some feedback from other engineers.
