Computer aided engineering (CAE): What is CAE and CAE software
Computer‑aided engineering lets teams simulate, analyze, and optimize designs before building, reducing risk, cost, and time with integrated CAE in Autodesk Fusion.

What is computer aided engineering (CAE)?
Computer aided engineering (CAE) refers to the application of computational methods and simulation technologies to evaluate and improve engineering designs. CAE allows engineers to predict how a product will behave under real‑world forces—such as stress, heat, vibration, and fluid flow—without relying solely on physical testing.
By using CAE simulation, teams can:
Identify potential design issues early
Compare multiple design options quickly
Reduce reliance on costly prototypes
Accelerate product development cycles
CAE is widely used across industries including automotive, aerospace, industrial equipment, electronics, and consumer products.

What is CAE software?
CAE software is a category of engineering software used to model, simulate, validate, and optimize product designs and manufacturing processes. CAE software applies physics‑based and mathematical models to analyze how parts and assemblies perform under various operating conditions.
Modern CAE software supports disciplines such as:
Structural and stress analysis
Thermal analysis
Fluid flow and heat transfer
Multibody dynamics and motion analysis
Multiphysics simulation
By integrating CAE software into the design process, engineering teams can improve product reliability, durability, and efficiency—while reducing development costs.

What is CAE simulation and how does it work?
CAE simulation is the process of digitally testing a product design using computer‑based models instead of physical prototypes. CAE simulation helps engineers understand how a design will respond to real‑world conditions before manufacturing begins.
A typical CAE simulation workflow includes:
Pre‑processing: Defining geometry, materials, loads, and constraints
Solving: Running the simulation using physics‑based solvers
Post‑processing: Visualizing and analyzing results to guide design decisions
This simulation‑driven approach enables faster iteration, better design decisions, and reduced risk before production.

Faster design iteration and validation
Access advanced simulation study types in computer-aided engineering software to validate real-world design performance through side-by-side design comparisons.

Improved product performance and reliability
By simulating real-world conditions, CAE software enables the prediction and improvement of product performance and reliability before manufacturing, ensuring optimal product functionality.

Lower costs and reduced time to market
CAE software allows virtual prototyping, reducing the need for costly and time-consuming physical prototypes, and speeding up the product development cycle.
Nonlinear Static Stress
With the ability to simulate large deformations, motion, and contact behaviors on nonlinear materials, this CAE capability is pivotal in predicting how materials and structures will respond under diverse stress conditions, thus enhancing design reliability.

Computer aided engineering (CAE) includes a wide range of simulation types, each focused on different physical behaviors.
Using Finite Element Analysis (FEA), CAE software can simulate and predict how a product will respond to physical forces like tension, compression, and shear. This helps engineers optimize and validate their designs to ensure durability and reliability.
CFD simulation analyzes fluid flow, airflow, and heat transfer. This is critical for applications involving aerodynamics, cooling, HVAC, and fluid systems.
Thermal simulation predicts temperature distribution and heat transfer within a product, helping ensure performance and reliability in temperature‑sensitive environments.
Multibody dynamics simulation evaluates motion, forces, and interactions between connected components—ideal for mechanisms, robotics, and vehicle systems.
Multiphysics CAE simulation analyzes how multiple physical effects, such as structural, thermal, and fluid behaviors, interact within a single model.
FEA is used to simulate stress, strain, and deformation in parts and assemblies. Engineers use FEA to validate structural integrity and make sure that designs can withstand real‑world loads.
