Defense related vehicles have very different engineering needs, focusing less on optimizing efficiency and more on military requirements
No industry sector encompasses a more diverse engineering span than the Defense Industry. While one of the most prominent areas of study would be aircraft, used by every major military in the world, equally important applications are found in the marine and ground vehicle industries too.
  • External Aerodynamics of a Hum-vee
  • STAR-CCM+ interface showing a trim volume mesh of a Hum-vee : STAR-CCM+ employs a pipeline methodology to ensure that the path from initial geometry to mesh can be easily and robustly automated. This meshing process may be carried out interactively or in batch.

STAR-CCM+ by CD-adapco allows for complex simulation analysis of new military equipment quickly and accurately, allowing rapid deployment of tools to meet the military’s needs. Our software also allows in depth and comprehensive study of highly complex systems, with an integrated toolset that requires no plugins or outside packages to run. CD-adapco offers solutions for the defense industry in areas including, but not limited to:


Of all the areas of the defense industry, aircraft requires the most precision in engineering. STAR-CCM+’s core functions center around giving accurate, well validated engineering results for aircraft design cheaply, quickly and efficiently. Just a few of the areas which the defense industry can use STAR-CCM+ for aircraft design are external aerodynamics, hypersonic flight, aeroacoustics, all forms of propulsion (jet, turbomachinery and propellers) and aircraft launch – particularly needed for VSTOL situations such as aircraft carrier launches. Please see our Aircraft Page for more in depth detail on what STAR-CCM+ can provide for your aircraft needs.

Ground Vehicles

While ground vehicles are not most commonly associated with CFD usage, companies have been using CFD software more and more frequently in optimizing them. An excellent example is the civilian car industry using CFD for reducing automobile drag. In the civilian sector uses are even more diverse than this. Military vehicles are required to operate in sometimes harsh and extreme environments, such as the deserts of the Mideast. Thermal management of the car’s engine in such extreme environments are critical to any military application. In the same vein, cabin ventilation and vehicle electronics cooling become enormously important.

Another aspect where CFD is critical is exhaust transmission. Battle damage to a vehicle could leak exhaust into the cabin if is not properly routed in the vehicle. Also, in a battlefield that is becoming more and more technologically sophisticated, being able to hide or disperse your exhaust heat from the eyes of infrared scanners becomes very helpful.


One of the most visible parts of the defense industry centers on maritime fleets. From submarines to aircraft carriers, and running the entire gamut of ship classes in between, a wet navy provides indispensable utility to any military. STAR-CCM+ brings new innovations to the maritime industry, such as allowing the creation of a virtual tow tank. With a virtual tow tank, a part or several parts of a ship may be swapped quickly, removing the need to spend time and money creating a new mockup every time the design changes. This allows for more iterations of design, creating a better product faster. Areas where STAR-CCM+ leads the industry in virtual tow tanks include ship hull analysis, submarine hydrodynamics and tube launched missiles.

Weapon Systems

STAR-CCM+ has several tools to help the entire defense industry in the design of new weapon systems. In addition to aerodynamic studies, our overset mesh setting allows the full analysis of separation events, which in turn allows a more in depth analysis of maneuvering fins attached to the weapon system. In addition, STAR-CCM+ is fully capable of analyzing the performance of a solid propellant engine.
