Digital twins are revolutionizing how we design, build, and manage physical assets and processes. Imagine having a virtual replica of your factory, wind turbine, or even your entire city, constantly updated with real-time data and capable of simulating various scenarios to predict performance and identify potential problems. This is the power of digital twins, and their impact is growing exponentially across industries.
Understanding Digital Twins: A Comprehensive Overview
What is a Digital Twin?
A digital twin is a virtual representation of a physical object or system across its lifecycle, using real-time data to simulate its behavior and predict future performance. It’s more than just a 3D model; it’s a dynamic, evolving entity that mirrors its physical counterpart.
