GT-SUITE v2025.1 Released!

Gamma Technologies is pleased to announce that GT-SUITE v2025.1 is ready for download.

Here are some selected highlights from v2025 and 2025.1!

Whether you are fine-tuning engines, optimizing for electrification, or leveraging multi-physics simulations, this GT-SUITE release shifts your designs into high gear! Below is a video highlighting some of the exciting new features that v2025 has to offer!

Machine Learning: Anomaly Detection and Data Classification Algorithms

GT-SUITE’s Machine Learning Assistant has been extended to support the creation, training, and export of anomaly or fault detection metamodels. These new types of metamodels allow specific fault characteristics to be detected (e.g. stuck valve, leaky pipe, etc.), a critical capability for digital twins. Additionally, GT-SUITE models can realistically simulate real-world faults that can be used to train these metamodels, instead of subjecting hardware to potentially damaging scenarios.

Batteries: Semi-automatic AutoLion model calibration and sodium-ion cell modeling

GT-AutoLion now includes a new wizard that walks users through the process of calibrating a GT-AutoLion model to experimental data, reducing the time required to calibrate these electrochemical models. GT-AutoLion also has new capabilities to model sodium-ion cells, allowing users to benchmark this new technology and how it performs in integrated systems.

Motors & Drives: New workflows integrating electric motors and inverters to solve for both NVH and system losses

GT-FEMAG and GT-PowerForge can now be set up to precisely calculate the interactions between a motor and its inverter. This includes the ability to account for the inverter’s pulse width modulation (PWM) strategy on system losses and noise, vibration, and harshness (NVH).

Vehicle Systems: New Microscopic Traffic Scenarios

Engineers can now study high-fidelity powertrain models in real-world conditions, factoring in the unpredictability of microscopic traffic and driver behavior. This enhanced approach, which utilizes GT-SUITE with SUMO (Simulation of Urban MObility), provides a more realistic assessment of vehicle performance and fuel/energy-saving potential in urban conditions.

Vehicle Dynamics: Run Fast for Controls Optimization

Experience unparalleled efficiency with our advanced 14 degrees of freedom (DOF) vehicle model. Faster than conventional 3D models, it empowers analysts to design and optimize control systems with ease. This model runs faster than real-time on the desktop enabling quick turnaround times for stability, handling and performance control algorithm development.

Thermal Fluids: Characterize complex components using GT-Auto-3DFlow

GT-Auto-3DFlow has been extended to allow the characterization of pressure drop, flow distribution, and heat transfer in complex components and plumbing, where 3D effects are important. An easy-to-use, guided wizard enables any GT user to perform accurate 3D flow simulations and the entire workflow remains in GT. This is an accurate, fast, and easy-to-use 3D flow simulation designed specifically for system simulation engineers.

Mechanics and Tribology: Flex-Flex EHD solution for Journal and Thrust Bearings

Journal bearing EHD (elastohydrodynamic) and thrust bearing EHD solutions have been enhanced to model flexibility on both sides, making it a flex-flex EHD solution. EHD solutions are critical in understanding the oil film behavior in heavily loaded bearings that operate in the mixed lubrication regime. Coupling elasticity on both surfaces of the bearing is critical in predicting the region of peak film/contact pressure and wear.

Batteries: Automatic Creation of Electrical and Thermal Battery Pack Model in GEM-3D

GEM3D v2025.1 propaation model GEM-3D now provides a new workflow to convert CAD geometry to battery cells (GT-AutoLion electrochemical or equivalent circuit models) and define how the cells are connected electrically and thermally to build a module or pack. This new workflow saves hours of model-building time over the old method to build an integrated model, by reducing the conversion and meshing time in GEM-3D and automatically building and integrating the electrical model.

Motors: New, More Powerful Template Geometries in GT-FEMAG

GT-FEMAG 2025.1 GT-FEMAG template geometries image has new template geometries for both rotors and stators. For rotors, a new interior permanent magnet geometry template for V-shape magnets now allows 1, 2, 3, or 4 pairs of concentric V-angled magnets. For stators, new geometry templates allow individual wires to be defined (round or hairpin) and AC winding losses can now be calculated with either a finite element approach or an analytical approach.

Motors: New Coupling between Electromagnetics and Thermal in GT-FEMAG

GT-FEMAG 2025.1 GT-FEMAG Coupling electromagnetics and thermal also offers the ability to run a 2D finite element thermal model to calculate the temperature distribution alongside the built-in electromagnetic motor models. This now allows hot spots to be detected and to calculate steady state max torque while adhering to temperature limits of the magnets and windings. Additionally, a thermal network including a map-based motor can be exported to run transient electro-thermal models in an integrated simulation.

Thermal Fluids: Optimize Passenger Comfort and Range in Real-time using an Auto-generated Cabin ROM

Updated Cabin ROM model GT can now automatically generate a physics-based, real-time capable 1D reduced order model (ROM) from a detailed 3D GT-TAITherm cabin model. This combines GT-SUITE’s and ThermoAnalytics, Inc.’s technologies, empowering users to quickly develop control strategies and evaluate various solutions to optimize passenger comfort and range. Learn more about this feature in this blog post.

Exhaust Aftertreatment: GT-xCHEM offers Cutting-edge Advancements in Exhaust Aftertreatment Modeling

GT-xCHEM now offers advanced exhaust after-treatment simulation capabilities including: v2025b1 xCHEM model

Advanced thermal models: advanced radiation (cavity) model
Advanced chemistry models: multiple reactivities, zoned & layered catalysts, predictive aging and zeolite modeling
State-of-the-art PM deposit and filtration models: deposit transport and capillary models
Detailed Lambda and NOx sensor models
Electrically heated catalysts

Also, users can now quickly and automatically convert their exothermia suite models to GT-xCHEM with the use of ET-Suite Migrator. A comparison tool is now available to automatically create graphs and compare exothermia suite and GT-xCHEM simulation results.

Productivity/User Experience: New “Smart Mode” to Run Simulations Efficiently

image (17) A new Run Simulation Wizard with Smart Mode is available for users to try. Smart Mode intelligently selects the most efficient execution method (local or local distributed) for your model. GT will automatically handle the details – no need to manually setup distributed computing. The Simulation Dashboard now fully supports both run modes for a consistent, user-friendly experience.

Model Management: Signal Explorer

image (16) Large, modular, system models have become increasingly more common as companies make the shift to more and more virtual testing. Signal flow in these modular models can become complex and very difficult to follow. GT’s new Signal Explorer provides a holistic view of signal and RLT usage across an entire model (including subassemblies, compounds, etc.). This includes both a “system view” of the signal flow between various files in a modular system model and also a detailed view to see specific information on each individual signal.
