Build, Validate and Deploy Hybrid Digital Twin Models

An analytics-driven, simulation-based digital twin is a connected, virtual replica of an in-service physical asset — in the form of an integrated multidomain system simulation —that mirrors the life and experience of the asset. Hybrid digital twins enable system design and optimization and predictive maintenance, and they 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.

Teaching AI brains using Digital Twins with Microsoft

From Digital Twin to Machine Learning: How it Works

ansys digital twin case study

Microsoft is working with Ansys Twin Builder software to create digital twins of equipment or processes to be automated using AI. Digital twins can generate the large amounts of data needed to train AI brains much more quickly and at a lower cost using physical machines for data generation. 

Engineers increasingly use artificial intelligence (AI) to automate processes and make decisions faster and more effectively than humans can. But, while engineers are experts in their area of specialization, most are not data scientists. And they don’t have the time to learn data science and write the complex code that AI modules require.

Microsoft Project Bonsai helps engineers create AI-powered automation without using data science by graphically connecting software modules programmed to perform certain AI functions. A complete set of connected functions that can perform a task is called a “brain.” A brain is a standalone, portable software module that can be used as part of an open loop to advise a human operator on the best decision to make. Or it can replace the human, making decisions and carrying them out by itself when configured in closed-loop mode.

Ansys Twin Builder creates connected, virtual replicas of an in-service physical asset

Ansys Twin Builder is a uniquely open solution that allows engineers to create digital twins–connected, virtual replicas of in-service physical assets. Digital twins enable true predictive maintenance, allowing for cost savings, and the proactive optimization of an asset’s operation. Ansys Twin Builder lets you build, validate and deploy the twin, potentially cutting the time required to create an accurate product model in half. Once deployed, users can expect a 25% increase in product performance, and maintenance cost savings of up to 20% over the product’s lifetime.


Key Features

Ansys Twin Builder features a wide range of capabilities for modeling and simulation of in-service assets.

  • Multidomain Systems Modeler
  • Extensive 0D Application-Specific Libraries
  • Third-party Tool Integration
  • Reduced Order Models (ROMs)
  • Embedded Software Integration
  • Multidomain Systems Solver with Integrated Post-Processing
  • Rapid HMI Prototyping
  • System Optimization Tools
  • XIL Integration
  • IIoT Connectivity and Twin Verification and Validation (V&V)
  • Twin Deployer
  • Hybrid Analytics
  • Export Web App from Twin Deployer

Create hierarchical schematics of complex power electronic circuits and multidomain systems. Model with standard languages and exchange formats.

Twin Builder models are easily parameterized to replicate physical component behavior. They include analog and power electronics components; control blocks and sensors; mechanical components; hydraulic components; digital and logic blocks; application-specific libraries for aerospace electrical networks, electric vehicles and power systems; and characterized manufacturers' components. Twin Builder supports the Modelica Standard Library and Modelica libraries offered by Modelon AB, including libraries for hydraulics, pneumatics, liquid cooling, heat exchangers and thermal power.

With over 100 tools now officially supporting FMI model export and cosimulation, including GT-SUITE, CarSim, Amesim and Dymola, full-system models can be assembled in Twin Builder to take advantage of its high-performing solvers and links with Ansys 3D physics. Additional interfaces allow the direct integration of C/C++ code and MathWorks Simulink models. Twin Builder models can also be exported for use in FMI-compliant environments.

Twin Builder uses ROMs produced from Ansys structural, fluids, electromagnetics and semiconductor products to model mechanical assemblies; electromagnetic actuators and machines; circuit and cable parasitics; thermal networks; and signal integrity. 3D ROMs can be created in Workbench and imported into Twin Builder. ROMs can also be imported from a variety of third-party tools, such as optiSLang. Co-simulation with 3D physics solvers preserves the full accuracy of FEA and CFD for modeling fluid components and flow networks, rigid and flexible-body mechanical assemblies, and electric machines and actuators. Get an easier access to all ROMs in one easy place with the ROM ribbon and gallery.

Tight coupling with Ansys SCADE Suite and SCADE Display permits interactive monitoring and debugging during software execution. Custom code and third- party controls can be incorporated into a Twin Builder system model through standard interfaces (e.g., FMI) or a robust API.

With adaptive time-step controls and sophisticated solver synchronization capabilities, Twin Builder performs efficient and accurate simulation of continuous-time, discrete-time and analog/mixed-signal behaviors. Twin Builder simulations can be executed on high-performance compute resources, and multi-run analyses can be executed in parallel to increase simulation throughout.

This enables you to create interactive panels using predefined widgets (buttons, sliders, etc.) to interact with the application under test. It empowers model simulation. Early requirements validation is made possible through a variety of features.

Twin Builder provides a full environment for testing system behavior, allowing basic simulation experiments to be performed in the steady-state, time and frequency domains.

Twin Builder provides links with popular embedded control design tools, including the Ansys SCADE tool suite and MathWorks Simulink.

Twin Builder's built-in APIs provide seamless connection to Microsoft® Azure® IoT, Microsoft Azure Digital Twins , PTC ThingWorx®, SAP Predictive Asset Insights, Rockwell Automation Emulate 3D and  Rockwell Studio 5000. Twin Builder can also connect to all other IIoT platforms, including homegrown varieties, allowing you to perform predictive maintenance on your physical asset. You can also easily deploy digital twins with Ansys Twin Deployer. Twin Deployer helps you significantly reduce deployment time by performing V&V on twins, and easily deploying the twin using cloud, edge or offline computing resources. Twin Builder also supports generating images from deployed twins.

User can build their dedicated library in Twin Deployer to easily reuse and manage your most common components. Easily perform parametric sweeps studies on twin and FMUs in Twin Deployer. With Ansys Twin Deployer,  Inspect 3D visualizations with ROM Viewer during simulation, thanks to ROM visualization generation capability. 

Fusion Modeling, a new capability to Twin Builder Hybrid Analytics, accurately models the residual between model and prediction, allowing users to capture and include any remaining or missing physics into the digital twin.
