Hard limitations
This page is the authoritative scope statement for cufemlab v0.3.0. If a capability is not listed under In scope, it is not implemented — and pretending otherwise violates platform rule #1.
In scope — v0.3.0-platform-mvp
| Domain | What is implemented |
|---|---|
| Magnetics | 2-D linear magnetostatic, 2-D nonlinear B-H via Picard, motor airgap flux, integrated motor workflow. |
| Thermal | Transient heat (1-D, 2-D), conjugate heat solid/fluid, motor slot-temperature path, GPU transient kernel. |
| Mechanics | Linear elasticity 2-D (CPU + GPU), rotor centrifugal stress, safety-factor reporting. |
| Fluids | Couette / Poiseuille (analytical-CPU OK), Stokes (Re=0) lid-driven cavity, conjugate heat coupling. |
| Materials | 53 cited entries (electrical steels, aluminium, copper, common coolants). |
| Reporting | Signed PDF/JSON/Markdown, SHA-256 provenance, full verdict trail. |
Not in v0.3.0 — explicitly deferred to v0.4+
| Capability | Target release | Rationale |
|---|---|---|
| CAD import (STEP / IGES / STL) | v0.4 (Phase U) | OpenCASCADE binding, 3–4 month effort. |
| Re > 0 Navier-Stokes (incompressible) | v0.4 (Phase E.2) | Add convection on SF-vorticity infrastructure; Ghia Re=100 target. |
| Nonlinear B-H integrated into motor workflow | v0.4 (J.1) | TEAM 32 ≤ 5% match. |
| Jupyter ipywidgets UI | v0.4 | Interactive geometry & sweep panels. |
| Parameter sweep + Pareto | v0.4 | Motor design exploration. |
| 3-D magnetostatic | v0.4 (J.8) | Memory + meshing work required. |
| 3-D elasticity / 3-D heat | v0.4 (C.2, B 3-D) | Memory + meshing work required. |
Permanently out of scope
These will not be added to cufemlab. If a customer needs them, refer to ANSYS, Maxwell, Star-CCM+, COMSOL, or a research code in the relevant field.
- Full Maxwell wave equation (RF, antenna, scattering).
- Turbulence modelling (k-ε, k-ω, LES, DES).
- Compressible CFD, transonic / supersonic flow.
- Eddy-current and high-frequency loss modelling.
- Multi-phase boiling FEM, two-phase flow with phase change.
- P2D (pseudo-2D) battery electrochemistry.
- Acoustic / vibroacoustic coupling.
- ASME-certified pressure-vessel analysis.
- Fatigue life prediction with damage accumulation.
- NVH (noise / vibration / harshness) for production sign-off.
cufemlab is not a replacement for…
cufemlab is a focused MVP for motor pre-analysis. It is not a drop-in replacement for ANSYS Mechanical, Ansys Maxwell, Siemens Simcenter Star-CCM+, COMSOL Multiphysics, or any commercial production-grade CAE suite. Use it where it shines — fast multi-physics pre-analysis with an auditable provenance trail — and use a production tool when you need a feature listed above.
Why this page exists
cufemlab's value comes from not over-claiming. If we say a domain passes, it passes against a cited benchmark within a declared tolerance. If a domain isn't here, it doesn't exist in v0.3.0. That clarity is the entire product.
If you find a documentation page, marketing claim, or output report that contradicts this page, the discrepancy is a bug — please email info@secrotec.com with the source so we can fix the inconsistency.
