Executable digital twin (xDT)

Deliver smarter products and processes by connecting the real and virtual worlds to unlock new insights. The executable digital twin lets you leverage digital twin models across the entire product lifecycle.

Connect the real and virtual worlds

To maximize performance, sustainability and cost efficiency, products and processes must be able to adapt to their environment and changes in operating conditions. Gain accurate insights in real-time by connecting real systems to virtual representations through rapid simulation models.

Build executable digital twin

Detailed digital twin models are developed to replicate real-world behaviors and packaged as standalone models using real-time methods like reduced order modeling (ROM) and artificial intelligence (AI).

Package

​The packaged form contains both the physics-based system behavior model and the solver needed to run it.​

The xDT is a real-time capable behavior model which can be connected to the live IoT data stream from a physical system.​

Leverage at scale

Once the detailed digital twin model has been developed, deploy on a connected edge device or on the cloud to start transforming Internet of Things (IoT) data into actionable insights that enable real-time adaptation and enhanced productivity in operations.

Multi-domain systems simulation

Maximize the return on investment by leveraging the digital twin of your thermo-fluid or mechatronic systems throughout the entire lifecycle. You can reuse the model built in the engineering phase as an executable digital twin to support procurement, commissioning and operations.

Perform a cost-based design optimization to minimize both capital and operational expenditures and support procurement operations. Connect the digital twin of your system to a virtual programmable logic controller to verify their interactions in a safe virtual environment before the system is built. Finally, by connecting the executable digital twin to the real system sensors and controllers via industrial IoT, you can augment the information available to the operators to maximize the efficiency and safety of system operations.

Finite Element based virtual sensing

Simcenter 3D supports the creation of Smart Virtual Sensors based on structural analysis. There are instances where physical sensors cannot be used to measure critical locations. This is where the Simcenter 3D Smart Virtual Sensing technology excels. It is specifically designed to overcome the limitations of traditional sensing methods.  By combining the limited physical measurements with a reduced order finite element model (FEM), it creates virtual sensors that provide insights far beyond the traditional methods.
