CARBONIZATION LAB
BCC foam on a substrate
Pyrolysis, gas escape and finite-strain contraction in a three-dimensional tetrahedral benchmark.
Rigid substrate at z = 0. Free control removes the bond and allows gas escape from all faces; the plate is a visual reference. Fine outlines show the initial dry geometry.
MODEL SCOPE
Illustrative material.
Explicit boundary conditions.
The BCC specimen is a voxel-derived tetrahedral union of struts. Finite-strain mechanics, volatile transport and material conversion are solved in Rust/Wasm; the viewport displays accepted node positions and local fields.
A perfect bond fixes contact nodes to a rigid, nonshrinking substrate. Network order is a structural surrogate, not an sp² fraction. Uniform temperature produces uniform solid chemistry in this one-way model; gas gradients do not feed back into char formation. The material is uncalibrated; predictions exclude cracking, delamination, evolving contact, gas-pressure forces and temperature gradients.
Use mesh refinement and the radial strut benchmark to inspect numerical behavior. The printing lab remains a separate preparation model; this benchmark does not simulate an imported Benchy.
