A simulation-based digital twin is a connected, virtual replica of an in-service physical asset — in the form of an integrated multidomain system simulation —which mirrors the life and experience of the asset. Digital twins enable system design and optimization and predictive maintenance, and optimize industrial asset management.

By implementing Ansys Twin Builder, you can improve top-line revenue, manage bottom-line costs and both gain and retain a competitive advantage. For example, digital twins will allow you to analyze predictive maintenance outcomes to save on warranty and insurance costs, and optimize your product’s operations.

To build your system easily and quickly, Twin Builder combines the power of a multidomain systems modeler, with extensive 0D application-specific libraries, 3D physics solvers and reduced-order model (ROM) capabilities. When combined with embedded software development tools, Twin Builder allows you to reuse existing components and quickly create a systems model of your product.

To validate your system and ensure expected performance, Twin Builder combines multidomain systems simulation capabilities with rapid human-machine interface (HMI) prototyping, systems optimization and XiL validation tools.

To connect your twin to test or real-time data, Twin Builder easily integrates with industrial internet of things (IIoT) platforms and contains runtime deployment options, allowing you to perform predictive maintenance on your physical product. It is the only product that offers a packaged approach for your digital twin strategy.

Meggitt’s Use of Twin Builder for Hardware/Software Cosimulation

Meggitt had to redesign the controller, including software, in a very short period of time. Using a SCADE-Twin Builder co-simulation approach, they were able to hit safety of flight in 7 months, and certify the entire product in just about a year.
