Key Concepts

Adaptive Meshing

Mesh refinement strategy where element size is adjusted based on predicted or actual stress concentration. Fine mesh where stresses are high, coarse mesh where they are low.

CAE (Computer-Aided Engineering)

Computer-Aided Engineering (CAE) is the software discipline and toolset for simulating the performance of a design under real-world conditions — structural loads, temperature, vibration, fluid flow — before the design is finalized for manufacturing. CAE is upstream in the product lifecycle. It consumes CAD geometry as input and outputs simulation results (stress maps, deformation plots, flow visualizations, temperature distributions) that tell the design engineer whether the design will work as intended.

CFD (Computational Fluid Dynamics)

Computational Fluid Dynamics (CFD) is the simulation of fluid flow, heat transfer, and related phenomena using numerical methods. CFD discretizes the fluid domain into a computational mesh and solves the Navier-Stokes equations (and turbulence models, combustion chemistry, or multiphase physics as required) to predict velocity fields, pressure distributions, thermal gradients, and mass transport. CFD is central to aerodynamic design, thermal management, combustion, HVAC, and any engineering context where fluid behavior determines performance or safety.

Design Optimization

Automated search through design space (geometry, material, topology) to find solutions that meet performance goals (minimize mass, keep stress below threshold, maximize stiffness) or objectives (maximize efficiency, minimize cost).

FEA (Finite Element Analysis)

Finite Element Analysis (FEA) is a computational simulation method that discretizes a physical structure into a mesh of finite elements to solve partial differential equations governing structural mechanics, heat transfer, and related physics. FEA predicts stresses, strains, deformations, vibrations, and thermal distributions in solid bodies under applied loads and boundary conditions. FEA is the foundation of structural simulation in CAE suites (Ansys Mechanical, Simcenter Nastran, Abaqus) and is used across aerospace, automotive, consumer products, medical devices, and civil engineering for design validation and certification.
