Simulations
that satisfy your requirements
Build your next simulation with FLAMES® and Unreal® Engine
FLAMES® is a family of commercial off-the-shelf (COTS) software products that provide a framework for developing custom constructive and virtual simulations and interfaces between live, virtual and constructive (LVC) simulations. The optional integration with Unreal® Engine extends FLAMES to provide the ultimate framework for the creation of serious games and visually stunning, entity-level constructive and virtual simulations.

SAVE MONEY
Start with a full-featured, working simulation framework instead of developing common simulation infrastructure from scratch. Develop only the software unique to your requirements while reducing the effort required to develop, test, and maintain your simulation.
SAVE TIME
Build on software that already exists. FLAMES provides the common infrastructure required by virtually every simulation, allowing you to focus on developing the software that models the real-world systems required by your program. Existing component plugins and source code can often be reused with little or no modification.
REDUCE RISK
Begin development with mature, COTS software that is already developed, tested, and in use. Rather than creating a new architecture for every program, build on a proven framework that has supported simulation development for more than 35 years.

SIMULATIONS
FLAMES has been used as the foundation for over 100 simulation programs developed by Ternion and other organizations. Decades of operational use, customer requirements, and continuous improvement have produced a framework that provides more capability from the start and continues to evolve as new requirements emerge.

Putting the tools in your hands
You control the design and development of your simulation. FLAMES gives you the tools to do it.
FLAMES Developer
Develop custom component plugins
The FLAMES Developer is the software development kit (SDK) and the tools needed to develop component plugins containing classes that simulate the behavior of real-world systems in accordance with your exact requirements. The classes in a plugin can also extend the functionality of the FLAMES Engine.
FLAMES Developer licenses are available at no cost. The FLAMES Developer also includes a Free Trial Version of the FLAMES Engine for evaluation and software development.
FLAMES Engine
Create, execute, visualize, and control scenarios
The FLAMES Engine is a set of applications that allow you to create, execute, visualize, and control FLAMES scenarios. These applications dynamically load the specified FLAMES component plugins to allow you to simulate almost any system in almost any scenario imaginable.
FLAMES and Unreal Engine
FLAMES and Unreal Engine create the ultimate framework for developing live, virtual, constructive (LVC) simulations. Try it today and bring your scenarios to life with the latest in gaming technology and the unparalleled power of FLAMES.
