Finite Element Analysis (FEA)

Finite Element Analysis (FEA) is the logical capability of solving partial differential equations governing structural, thermal, electromagnetic, or coupled physics problems by discretizing the domain into a mesh of finite elements. It is the core method underlying virtual product validation across nearly every engineered industry.

What it covers

• Linear and nonlinear static analysis (small and large deformation, plasticity, contact).
• Modal, harmonic, and transient dynamics including random vibration.
• Thermal and thermo-mechanical coupling for heat transfer and induced stress.
• Explicit dynamics for crash, drop, and impact events.
• Fatigue and durability post-processing from stress histories.

Relationships (see sidebar)

• Supports the CAE Analysis process.
• Implemented by systems like Siemens NX (Simcenter / Nastran) and Dassault 3DEXPERIENCE (Abaqus / Simulia).
• Specialist counterpart to designer-tier CAD Simulation.
