Fast 3D Flow Solver
Rapid CFD computation embedded directly in system-level models.
Fast, Accurate 3D Flow Designed for System Simulation Engineers
PRODUCT OVERVIEW
What is GT-Auto-3DFlow?
GT-Auto-3DFlow is a fast and accurate 3D flow solution developed specifically for system simulation engineers without 3D CFD experience. This empowers GT-SUITE users to increase simulation accuracy when 3D effects are important, including airflow over heat exchangers or characterizing complex components.
GT-Auto-3DFlow, which is tightly integrated into GT-SUITE, is the result of a collaborative development between GT and Simerics. Features like automated meshing offer remarkable ease of use, creating a seamless workflow that exists entirely within GT-SUITE.
REDUCE DEPENDENCE ON OTHERS
Faster Design Cycles
System simulation engineers can enhance the accuracy of their models by leveraging 3D flow simulations. However, communication delays and sometimes differing priorities between 1D and 3D teams can lead to inefficiencies and extend development cycles. By empowering 1D simulation engineers to conduct their own 3D flow simulations, the design process can be streamlined, allowing them to take control of their project timelines and drive innovation more effectively.
INTUITIVE WORKFLOW
Ease of Use
The entire workflow exists in GT-SUITE, beginning with an easy-to-use guided multi-step wizard in a 3D environment. No previous CFD experience is required, and within a few minutes, the model is ready to run. Meshing is fully automated and results are post-processed directly in GT-POST.

USE CASES
-
Airflow with Heat Exchangers & Fans
The integration and mapping of the 3D airflow solution and 2D heat exchangers is handled automatically by Auto-3DFlow enabling accurate non-uniform distribution of velocity and heat transfer. The solution is highly flexible and allows a single model to vary heat exchanger sizing and positioning, number of fans and their location, active grill shutter angles, and more. These changes can be driven by the built-in design optimizer as well. Behind the scenes, the automated meshing handles all these geometry changes. Heat exchanger and fan performance is calculated by the advanced physical models available in GT-SUITE for decades.
-
Flow & Thermal Characterization
The fast and accurate GT-Auto-3DFlow steady-state solver predicts pressure losses, flow distribution, and heat transfer coefficients for complex geometries. These results are easily transferred to system simulation models to improve accuracy where 3D flow effects are important, while maintaining fast simulation speeds.
-
Conjugate Heat Transfer
For higher fidelity conjugate heat transfer, GT-Auto-3DFlow integrates with the native thermal finite element solution in GT-SUITE. GEM3D handles the model setup and mapping between the fluid and structure, delivering a streamlined workflow.
