CivilKit Studio - a browser-based 3D structural analysis & AS-code design tool. Everything runs locally (WebAssembly solver); nothing is sent to a server.
Solver verification
Analytical benchmarks25/25 pass closed-form to 1e-4 - cantilevers, simply-supported & continuous beams, propped/overhanging, fixed-fixed, L-frame bent, 2D/3D trusses, torsion
PyNite parity0.0000% signed - displacements + reactions, random 3D frames (nodal / UDL / point loads, varied supports)
Reference oracleindependent numpy solver, signed across 6 DOFs
Physics invariantspass equilibrium (ΣR = Σapplied to machine precision, 17 models), Maxwell-Betti reciprocity & load superposition - asserted through the solver
Section data425 sections across 6 codes - mass & Ix cross-checked to dimensions
Platesanalysis only (displacements + stresses); coarse-mesh accuracy is under mesh-convergence validation - not yet a design check

Always confirm restraints, effective lengths and the governing combination before relying on any design result.
