GT-SUITE is a multi-physics, multi-dimensional simulation software suite developed by Gamma Technologies (GTI), specializing in model-based engineering (MBE) for powertrain, thermal management, and vehicle systems. It supports 0D/1D/3D modeling across industries like automotive, aerospace, marine, and energy, enabling rapid prototyping, optimization, and virtual testing. Version 2025.2 is a minor patch release in the 2025 series, emphasizing reliability over major overhauls. Released on July 29, 2025, it builds on the foundational updates from v2025.1 (April 2025), which introduced significant enhancements in electrification, thermal systems, and AI-driven workflows.

Key Updates in GT-SUITE 2025.2

As a minor release, v2025.2 focuses on maintenance and user experience rather than new groundbreaking features. Highlights include:

Category Description Benefits
Security Enhancements Updated third-party libraries to address vulnerabilities, ensuring compliance with modern cybersecurity standards. Protects sensitive simulation data and integrates better with enterprise environments.
Stability Improvements Fixes for crashes in large-scale simulations, particularly in GT-Power and GT-Thermal modules. Reduces downtime during complex workflows like engine calibration or battery thermal runaway analysis.
Robustness Across Modules General optimizations for solver convergence in multi-domain models (e.g., eDrive systems with GT-ELECTRIfi). Improves accuracy in transient simulations for hybrid/electric vehicles and HVAC systems.

For major features of the 2025 series (introduced in v2025.1), refer to the table below. These form the core of what users experience in 2025.2:

Feature Category Key Additions in 2025 Series Applications
Electrification & Batteries Enhanced GT-AutoLion for side reaction modeling in thermal runaway; improved state-of-charge estimation with machine learning. EV battery design, safety mitigation, and fast-charging optimization.
Thermal Management Advanced conjugate heat transfer in GT-Turbo and GT-Cool; integration with GT-xCHEM for combustion-thermal coupling. Engine cooling, exhaust aftertreatment, and cabin climate control.
AI/ML Integration New metamodeling tools (e.g., deep neural networks, Sobol sensitivity analysis) via GT-ISE; automated design exploration. Rapid surrogate modeling, parameter calibration, and DOE (Design of Experiments) for reduced computation time.
Optimization & Calibration Upgraded optimizer with parallel processing support for PEST-like estimation; export to external tools like MATLAB/Simulink. Multi-objective optimization for fuel efficiency and emissions reduction.
Migration Tools Free ET-Suite Migrator for transitioning from legacy Exothermia Suite to GT-xCHEM (support ends Dec 31, 2025 for new licenses). Seamless upgrades for thermal/chemical simulations without data loss.
