Examples

Examples are executable parts of the software, not screenshots of possible features. Each example identifies the physical problem, numerical route, important output, and present maturity. Release examples carry numerical contracts; engineering examples exercise broader workflows that still require problem-specific qualification.

Science supershear data protocol

examples/science_supershear_v5_protocol.py verifies the pinned Dryad file identities and inventories the public Science 2023 crack-speed, wave-speed, Mach-cone, material-response, and SED/KED workbooks. It is the data boundary for the Science Supershear V5 protocol, not a parameter fit disguised as an example.

2D static elasticity

Release

A compact cantilever demonstrates Study, mesh, named boundaries, displacement, isotropic elasticity, strong constraints, traction, a linear step, standard U/S/E/MISES output, a Golden observable, and release-quality verification.

Transient heat transfer

Release

This case exercises capacity and conduction operators, backward-Euler time integration, accepted-increment progress, temperature histories, unified field output, and a release Golden observable.

Wave packet with an inclusion

Release

An explicit wave propagates through a heterogeneous two-dimensional solid. The case combines material regions, a time-dependent source, boundary models, stable time integration, probes, progress events, and time-series fields.

Abaqus periodic hyperelastic cell

Engineering

This workflow directly imports an Abaqus C3D10H mesh and equation constraints, preserves quadratic-node and hybrid/constant-pressure identity, solves a P2/DG0 finite-strain Neo-Hookean problem with exact periodic constraints, and writes homogenized and visualization results.

Read the complete periodic-cell workflow before running the case; it explains the source files, element mapping, periodic semantics, nonlinear controls, and output.

Implicit creep relaxation

Engineering

A three-dimensional power-law creep problem exercises quadrature state, backward-Euler constitutive integration, analytical consistent tangent, physical-time automatic incrementation, rollback/cutback, creep output, energy evidence, and restart. The same global step can consume a prescribed temperature field through the Arrhenius material factory.

Hot-wall creep assessment

Engineering

The hot-wall case performs a thermal/thermoelastic finite-element workflow and then an explicitly identified local creep assessment. It demonstrates how the software distinguishes a global field solution from a material-point or assessment-level model.

Elasticity surrogate campaign

Release

The campaign varies declared parameters, runs the same finite-element model, records failures and evidence, creates an accepted scientific dataset, trains a surrogate, checks its applicability domain, and retains an FEM fallback.

Reading an example

Do not copy only the final solver call. Read the Study, dimensional assumption, mesh and regions, material data, loads and constraints, procedure, output request, result policy, and benchmark evidence as one scientific workflow. When adapting an example, any change to physics, discretization, material law, or loading may require new verification evidence.
