Simulation & design
Designing and testing digitally before building physically.
Simulation lets engineers test a design before committing to physical hardware. They can examine how air moves around a vehicle, whether a component overheats or where a production line becomes congested. Design software defines the product; simulation predicts its behaviour. The customer buys a way to compare options earlier, when changing a file is cheaper than rebuilding a machine.
This theme includes computer-aided design, engineering simulation, manufacturing software and digital twins. A useful twin connects a model to information about the real asset; a detailed 3D picture alone does not predict performance. Smaller suppliers may develop specialist software or sell implementation, training and support around larger platforms. Those roles have different margins and dependence on platform owners.
Market size & opportunity
CIMdata’s July 2026 market-report release estimates global simulation-and-analysis revenue at US$11.67 billion in 2025 and forecasts just over US$12.78 billion in 2026. That is the simulation-and-analysis segment, not all design, construction or product-lifecycle software. The figures below this theme’s broad label should therefore not be added indiscriminately to software-market totals.
Demand depends on engineering programmes, the number of users and the amount of computation required. A reseller may earn only part of a software sale plus service fees; an owner of specialised software has different economics. Renewal rates, usage and the cost of supporting complex deployments help show whether a growing installed base is becoming a better business.

Recent progress
AI can help engineers explore more designs between expensive full simulations. Siemens announced Simcenter PhysicsAI on 27 May 2026. The software learns from computational-fluid-dynamics results and uses them to predict how other shapes will perform. These are faster approximations trained on simulation data. Their usefulness depends on validation and on whether a new design stays within what the model can handle.
In July 2026, NVIDIA released Omniverse libraries for sensor simulation, accelerated physics and checking whether 3D assets are ready for simulation. That can make these capabilities easier to integrate into existing engineering tools. It does not remove the need for sound input data and physical tests. A model can calculate confidently from the wrong assumptions.
