Unlock the potential of Twin Builder CFD with our comprehensive guide to building, validating, and evaluating Static ROM.
Challenges
CFD (Computational Fluid Dynamics) application of Twin Builder is a powerful tool used in the simulation of fluid flow and heat transfer. It offers a detailed analysis of the interactions between fluids and surfaces, crucial for designing efficient systems.
Developing and validating a static ROM is not without challenges. Common issues include ensuring model accuracy, handling large datasets, and maintaining computational efficiency.
Addressing these challenges requires a deep understanding of both the CFD processes and the underlying physical phenomena being modeled.
Engineering Solution
A digital twin with a reduced order model (ROM) can help engineers to overcome the challenges of ROM development by leveraging advanced tools and methodologies. Twin Builder provides robust capabilities for model reduction, validation, and optimization.
A ROM is a simplification of a high-fidelity model. it preserves the essential and dominant behavior. Provides real time physical prediction with less computational sources in orders of magnitude faster times with a high accuracy. In Ansys Twin Builder ROMs are classified base on the output behavior as static or dynamic (Figure 1).

In this blog, we demonstrate a static ROM application on a simple 2D mixing elbow geometry. The Fluid flow analysis was carried out by Fluent for number of different magnitudes of velocities at large and small inlets (Figure 2).

The steps to build, validate and evaluate the ROM are summarized as follows:
1. Open Ansys Twin Builder, and launch a Static ROM (browse the folder to open the already prepared files)
2. Once all the design points loaded, explore the snapshots (Figure 3)
Figure 3. Explore the design points
3. Build the ROM with modes reduction. Add the design points with high errors to enhance the model (Figure 4)
Figure 4. Build the ROM, modify to improve the ROM prediction
4. Validate the ROM predictions relative to the reference (the Fluent results - Figure 5)
Figure 5. Validate the ROM for all design points
5. Export the ROM to Twin Builder.
The details of these steps can be found in the attached video.

Benefits
The primary benefit of using static ROMs is the significant reduction in computational time and resources. This enables faster simulations and more efficient design iterations.
Additionally, ROMs facilitate real-time analysis and decision-making, which is critical in dynamic and high-stakes environments.
