Problem Statement

The Pain

Finite element analysis is a core engineering tool across aerospace, automotive, and energy, but the workflows around it are broken in practice:

• Meshing is the bottleneck. In complex assemblies — crash models, large multi-component structures — generating a mesh of satisfactory quality can take longer than the solve itself. A crash simulation may solve in days on high-end hardware, but the meshing step routinely takes over a week.
• Mesh quality drives everything downstream. Poor meshing is the single most common cause of inaccurate results and wasted compute. Engineers iterate manually, often re-meshing multiple times before a valid run.
• Multi-physics models compound the problem. Even when geometry is automation-friendly, as in WAAM process simulation, each parametric study requires a week or more of solver time per model — and the mesh must be right before the solve starts, or the cost is sunk.

The result: engineers spend disproportionate time on the least-valuable part of the workflow — manually iterating on mesh density — while compute costs accumulate and project timelines slip.

Who Feels It

Aerospace and automotive OEMs and their Tier 1 suppliers — organisations that run large numbers of non-linear or contact-heavy FEA models and are already investing heavily in simulation. These teams have the most to gain from reducing meshing iteration time because their models are the most complex and their validation requirements are the strictest.

Critically, the buyer is the simulation team and the CAE manager — not IT procurement or the C-suite. This shortens the sales cycle for early contracts and ensures the product is evaluated by practitioners, not administrators.

Why Now

Three converging forces make this the right moment:

1. GNN-based mesh learning has matured. Graph neural networks can now tokenise 3D geometry and learn refinement policies from structured simulation data — something that was not feasible five years ago.
2. Open-source solver ecosystems are production-ready. CalculiX and similar solvers are used in real aerospace and automotive workflows. The product does not need to displace entrenched commercial solvers; it interoperates with them.
3. Compute costs are rising and scrutiny is increasing. Every re-run due to poor meshing is a measurable cost in engineer-hours and cloud spend. Organisations are actively looking for tools that reduce iteration without compromising traceability.

Why Not End-to-End AI

End-to-end AI solvers that output predictions without running a validated FEA model cannot be accepted in regulated industries. This is a regulatory and contractual constraint, not a preference — aerospace and automotive certification processes require traceable, physics-based results.

FEA Sidekick does not compete with existing solvers. It wraps around the solver the engineer already uses, requires no change to the validated simulation chain, and produces interpretable, auditable outputs. This is why the wedge is model-aware meshing: it reduces the most expensive manual step without touching the solver or breaking certification workflows.

The full technical phased approach is documented in the Technical Roadmap.
