CAD & FEA.

Modelling, drawings, structural simulation.

Overview

Parametric CAD, technical drawing, structural / fatigue / thermal FEA. Production-grade documentation.

Parametric CAD, full GD&T technical drawings, and the FEA that justifies them, structural, fatigue, thermal, NVH. Documentation that passes a supplier’s first read and an auditor’s second.

The discipline is making the numbers honest. A FEA result is only as good as the boundary conditions and the mesh convergence behind it; a GD&T drawing is only useful if the datum scheme supports the assembly function. We write down why, not just what. The report tells you how much the answer could be wrong.

Process

How we'll run the programme.

Model Definition

Design intent captured parametrically. Master models, position-critical features, and mate references defined for the full assembly tree.

Analysis

Structural, fatigue, thermal, CFD where relevant. Mesh convergence documented. Boundary conditions justified from first principles.

Drawings

GD&T per ASME Y14.5 or ISO 1101. Datums selected to support assembly function, not cosmetic ease. Drawings a supplier can quote without phoning back.

Release

Production-grade documentation pack. Drawings, BOM, analysis report, material spec. Revision control matched to your PDM.

Capabilities

Modelling, drawing, and simulation, together.

Parametric CAD

Master-model approach, feature suppression logic, and fully constrained sketches. The model updates when the load case changes, with no sketch-repair rework.
GD&T to ASME Y14.5 / ISO 1101

Datum scheme derived from assembly function. Tolerance chains closed analytically. A drawing a supplier can quote without a phone call.
Structural FEA

Linear static, non-linear, and buckling analyses. Mesh convergence documented per element type. Result uncertainty quantified, not just reported.
Fatigue & Durability

S-N and ε-N fatigue analyses with Miner's rule and notch correction. Load spectrum defined from duty cycle, not assumed.
Thermal Analysis

Steady-state and transient thermal FEA, CFD-informed boundary conditions. Heat-transfer coefficients measured where literature values carry uncertainty.
Topology Optimisation

SIMP-based topology runs as a design space scout, not a black-box. Results interpreted and engineering-filtered before geometry extraction.

Quality metrics

What production-grade looks like.

100%: First-article pass rate; Drawings passed supplier FAI without revision
< 2%: FEA result uncertainty; After mesh convergence and BC validation
0: Supplier RFQ call-backs; GD&T queries on released drawings
ISO 1101: Drawing standard; ASME Y14.5 also available on request
