Code and result files for "Wall thickness and layer order in the thermal conductivity of TPMS sheet lattices: a Gaussian-curvature correction"

Research data of the article “Wall thickness and layer order in the thermal conductivity of TPMS sheet lattices: a Gaussian-curvature correction”. The deposit holds the layer-conforming quadratic tetrahedral finite-element solver of the periodic conduction cell problem, the layer (class) model, the voxel/FFT solver and the finite-specimen solver; the fitted Fourier minimal surfaces (Gyroid, Schwarz D and P, I-WP, Neovius, F-RD and tetragonal D and P); one JSON file per run of the twenty-eight numerical campaigns S1 to S28 (among them pore-gas conduction, interfacial resistance, grid convergence indices, an independent finite-element check on the Gyroid and on I-WP, two-sided bounds, second-order theory for eccentric and laminated walls, eccentric and one-sided walls on I-WP and F-RD, which have no symmetry exchanging the two sides of the surface, surface invariants that change sign between the two sides, a virtual measurement design, thickness scatter, a component-scale check and a check of the surface fit against exact Weierstrass–Enneper surfaces); the tables built from those runs; and the script that draws every figure of the article and its Supplementary Information. All code is Python 3 (NumPy, SciPy, pandas, Matplotlib, scikit-image; SymPy for one symbolic check only; scikit-fem and PyAMG for the independent finite-element checks of campaigns S16, S26 and S28 only) and lives flat in code/, so every import resolves from the package itself. Results are in results/S0 to results/S28 (tables) with the per-run JSON in results/S<k>/runs. The tables of every campaign that has tables were regenerated from the shipped runs with the shipped scripts and matched the deposited tables (S27 has no tables; the S18 model file needs uncached geometry arrays, see the README). README_dataset.md maps each file to the table, figure and section it supports, gives the commands that rebuild each block and the figures, and lists what is not deposited (caches, console logs and shell launchers).
