AgentFEM 0.3.0¶
AgentFEM 0.3.0 is the first release built on a stable scientific middle layer between humans or AI agents and the FEniCSx/PETSc numerical runtime.
One public workflow¶
The recommended language is:
Model remains a readable engineering facade. Constitutive owns material
updates, State owns committed and trial history, Operator owns mathematical
contributions, Procedure owns numerical evolution, Backend owns finite-element
execution, and Result/Verification owns evidence and acceptance. Architecture
tests keep these responsibilities from silently collapsing back into one
numerical god object.
Evidence-bound execution¶
The same execution lifecycle now carries solver options, output, history, progress and checkpoint policy. Structured results retain convergence, balances, failures, provenance, scientific quantities and artifact integrity. Capability maturity remains bounded by executable Golden, failure, MPI or external evidence rather than by the existence of an API name.
Open extension seam¶
AgentFEM-Learning demonstrates that a separately installed package can
register neural-field and finite-domain XDEM providers without modifying the
core. The extension is discovered through the same provider boundary and
returns the same SimulationResult contract used by deterministic workflows.
Human and agent acceptance¶
The release candidate passed clean installed-wheel acceptance on hosted Linux and macOS. A genuinely fresh Codex session then consumed the immutable wheel, inspected the runtime, constructed and refined a plane-strain cantilever, verified force and work balance plus artifact integrity, and explained the model assumptions without human correction. These are behavioral acceptance conditions, not deterministic CI substitutes.
Scientific foundation in this release¶
The 0.3 foundation includes reviewed Abaqus migration, solver-neutral user materials, transient and nonlinear State transactions, finite-strain J2 RVE workflows, mixed-mode LEFM extraction, cohesive and creep foundations, parameter campaigns, scientific datasets and learning interfaces. Each keeps its declared maturity and applicability boundary.
Scope¶
AgentFEM 0.3.0 does not claim universal element, material, contact or fracture coverage. Native Windows, general contact, arbitrary-path fracture, monolithic thermo-mechanical coupling, and automatic PINN or neural-operator training for arbitrary meshes remain outside the release claim. WSL2 remains the recommended Windows route and a separately tracked platform target.
