FEAT3D - Demo

FEAT3D — Finite Element Analysis Toolbox 3D Version v1.10.x — Cross-platform structural analysis for engineers Model, analyze, and visualize 3D structures with professional-grade accuracy — without the enterprise price tag. FEAT3D combines an intuitive 3D modeling environment with a fast native solver, AISC 360‑16 and ACI 318‑19 code checks, and shape‑aware rendering that shows members as they really are. Perfect for preliminary design, conceptual studies, prototyping, teaching, and rapid iteration — get reliable insights early in your workflow, then verify final designs with licensed professional engineers. Windows • Linux See your structure — not just lines Members render as actual cross‑sections: W‑beams, HSS tubes, channels, angles, tees, and concrete shapes. What you model is what you see. Real code checks you can trust AISC 360‑16 LRFD — flexure, shear, compression, torsion, combined forces, and von Mises stress ACI 318‑19 — flexure, axial, shear, torsion, and combined interaction for reinforced concrete Per‑member PASS/WARNING/FAIL results with color coding Full PDF engineering reports Built to handle real problems Modeling 2D & 3D frames and trusses Steel + reinforced concrete (rectangular, T‑beam, L‑beam, circular) AISC v15.0 section database (all 13 shape types) Custom section editor — enter 2‑4 dimensions, get 18 properties instantly Grid snapping, multi‑plane grids, keyboard shortcuts Undo / redo Loads & Analysis Nodal loads, distributed loads, point loads, concentrated moments Multiple load cases with combinations P‑Delta second‑order analysis Buckling analysis Thermal effects Self‑weight Moving loads (HL‑93, EU LM1, UK HA) Results & Output Deformed shape visualization (scale‑controlled) Member force diagrams (axial, shear, moment, torsion) Deflection diagrams PDF reports (includes stiffness matrices on request) CSV / JSON export Influence lines Reinforced concrete support 4 section shapes: RC_RECT, RC_TEE, RC_L, RC_CIRCLE ACI 318‑19 code checks (§22.2, §22.4, §22.5, §22.7, H1.1) Rebar library — #3 through #18 with ties / spiral reinforcement Branson’s cracked‑section Iₑ (ACI §6.6.3.1) Transparent display to see rebar inside concrete Bridge & building generators Warren‑truss pedestrian bridge — multi‑span, automatic supports Steel plate girder highway bridge — built‑up girders, cross‑frames, deck Multi‑story moment frame with bracing Drilled shaft sample model with soil springs System Requirements Windows 10+ (64‑bit) Linux — glibc 2.31+ (Ubuntu 20.04+, Fedora 32+, Debian 11+) OpenGL 2.1+ (3.0+ recommended) 4 GB RAM (8 GB for large models) ~200 MB disk space Registration A registration key is required to remove the periodic reminder popup. One‑time internet verification via Gumroad (https://bouness.gumroad.com/l/feat3d), then fully offline. Important: The installer binary is the only distributed form. Designed for preliminary engineering & education FEAT3D is an excellent tool for: Conceptual and preliminary design — quickly compare alternatives Prototyping structures — test ideas before detailed design Teaching and learning — visual, interactive FEA Self‑checking — cross‑validate hand calculations Always have final, safety‑critical decisions independently verified by a licensed professional engineer. 📜 Disclaimer THIS SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT.
