Free calculators give you a single averaged k. Full CAE platforms are custom-quoted and built for multiphysics workflows. This tool sits in the gap: enter your constituent conductivities and geometry, get k∥ (along the structure), k⊥ (across it), and the anisotropy ratio — in under a minute, in your browser.

Free tools (Engineers Edge, TrueGeometry, and similar) apply one mixing-rule formula — series or parallel — to a volume fraction and two conductivities, and hand back one isotropic number. That’s fine for a sanity check, but it’s wrong for anything with structure: layered PCB stacks, freeze-cast ceramics, battery jelly-rolls, aerospace composite panels, nacre-like brick-and-mortar architectures, aligned-fiber reinforcements. Those materials conduct heat differently along different axes — sometimes by 10× or more.
The other option is a full CAE platform, custom-quoted and scoped around thousands of core-hours — built for engineers running full multiphysics workflows, not for someone who needs one directional k-tensor answer today. This tool answers that one question directly, with the method shown, not a black box.
Runs entirely in your browser — nothing is uploaded. This is the same physics validated in R&D against a full finite-volume homogenization solver (see the method note under each result).
Laminate, brick-and-mortar (nacre-like), or aligned-fiber (square-packed).
Two constituent conductivities and a solid volume fraction (plus aspect ratio for brick).
Every result ships with a method note — what’s exact, what’s a validated bound or approximation, and its known accuracy range.
