The effects of media such as gases, liquids or bulk materials on components or systems remain hidden to our eye in most cases. The same applies to heat that is added or dissipated in components. CFD simulations make pressures, flow forces and heat flows visible. Thus, calculations in the field of fluid mechanics offer you valuable insights in product and process development.

CFD simulations allow you to know in advance which design makes sense, where you need to adapt components or how to design your product to achieve the highest possible efficiency. The applications of CFD simulation are manifold. The information you can gain from it is enormous.

Comprehensive insight

CFD calculations can be used to better understand and combine the relationships between pressure, temperature, resulting losses and efficiencies in flowing media, also in connection with chemical reactions. Mixing processes, multiphase flows, free surfaces and particles can also be investigated. Even the acoustic behavior can be analyzed and occurring noise can be reduced.

Efficient development

CFD analysis allows you to detect turbulence, critical temperature gradients and resulting thermomechanical stress peaks early in the design phase. Vary different designs quickly and without costly prototypes and thus optimize your product within a very short time. An enormous time gain!

Quick error analysis

If efficiencies are too poor or temperatures are too high or too low, equipment is too noisy, or mixing processes are inadequate, CFD analysis can offer you insightful insights into finding and fixing the root cause.

Competitive advantages through efficiency and safety

CFD analysis can be used to prove the effectiveness of your system, fan or pump. In addition, the optimal design is found quickly. You save costs and maximize the safety of your product!

When does CFD make sense?

For product development, failure analysis and numerous other applications - from engine cooling to bulk solids processes to cleanrooms, computation of fluid dynamics provides valuable support:


On the development of functional flow-optimized coarse geometries.

To develop ideal assembly models and designs, optimize efficiencies, minimize losses.

Validation of the function

Functional tests

Product variants

Validate design variants including functional and flow tests: 

Apart from material behavior, design also influences thermal behavior. CFD simulations can be used, for example, to reduce the temperature peaks on a printed circuit board by placing the electronic components differently (thermal management). 

The efficiency of entire industrial processes can also be optimized with the help of computational fluid dynamics.

Damage analysis

Fault analysis and correction: 

Untraceable damage to industrial equipment, recurring component failures, unintended damage due to overheating, and more can often be explained using CFD calculations. Damages have to be explained, repaired and avoided in the future. Especially in the prevention of further, future damage, CFD analyses provide important data for design and layout to avoid stresses in the component or overheating and to optimize cooling.
