Engineering Analysis (CAE practice)

Engineering Analysis (CAE) is the engineering practice of using simulation to predict and validate product behaviour — structural, thermal, fluidic, electromagnetic, multibody — before physical prototypes are built. It is not a standalone lifecycle phase — it is a discipline applied throughout Detailed Design and Verification & Validation to compress iterations and surface failure modes when changes are still cheap.

What the practice covers

• Idealizing the CAD geometry, meshing, applying loads and boundary conditions.
• Running FEA / CFD / MBD / EMAG / coupled-physics solvers.
• Post-processing results and feeding insights back to CAD Authoring.
• Simulation Process and Data Management (SPDM) — keeping CAE inputs, models, and results inside the CAD/PLM record rather than scattered network shares.

Relationships (see sidebar)

• Realizes Time to Market, Product Quality, and First Time Right by catching defects pre-prototype.
• Supported by the underlying logical capabilities — FEA, CFD, CAD Simulation, Tolerance Analysis.
• Embedded in Detailed Design and Verification & Validation; iterates with CAD Authoring across the design–analyze–revise loop.
