We've spent a decade talking about digital twins on the factory floor, and today real plants in Spain have twins that actually work. Of the four typologies (asset, process, plant, and product), three have proven return; the product twin remains more promise than reality. A look at which platforms are winning, where the twin pays for itself, and what is still hype.
A digital twin is a software replica of a physical asset (machine, production line, or whole plant) synchronised in real time with IoT sensors. It enables failure prediction, energy optimisation, and operator training without risk. It returns real value when the asset is critical, the data is reliable, and the team can maintain the model long-term.
The best digital twin tools fall into three categories: simulation (ANSYS, Siemens NX, COMSOL, Dassault SIMULIA), virtual-reality visualisation (Unity, Autodesk VRED, Blender), and lifecycle management or PLM (Siemens Teamcenter, PTC Windchill, Aras). The right choice depends on your sector, asset type, and the integration budget with your existing operational systems.
