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:

  1. Pre‑processing: Defining geometry, materials, loads, and constraints
  2. Solving: Running the simulation using physics‑based solvers
  3. 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.
