# SimWiki¶

Simulation Wiki is a place where the most important terms related to computer-aided engineering are explained.

Within this Wiki, you will find explanations of concepts, features, equations in connection with Finite Element Analysis, Computational Fluid Dynamics and Thermal Analysis.

**What is engineering simulation?**

Engineering simulation, also know as computer-aided engineering (CAE), refers to the use of sophisticated graphical software to analyze designs and solve engineering problems. CAE includes Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), Thermal Analysis, Multibody Dynamics and Optimization.

**Understanding CAE**

Used primarily in Aerospace and Automotive since the 1950s, nowadays computer-aided engineering is standard in almost all industries, from Heavy Equipment, HVAC and Manufacturing to Consumer Goods and Electronics for simulating, validating and optimizing product designs.

Fluid flow, mass and thermal transport, fluid-solid interaction, static or dynamics analysis, stress analysis on components and assemblies, conjugate heat transfer, conduction, convection, radiation and more can be tested for a wide range of designs, using CAE software.

The main purpose of CAE is to test, predict and improve the robustness, performance, energy efficiency and durability of components and assemblies, in the end creating better products and reducing the number of required physical prototypes and the time to market.
