CFD simulation: high-precision flow analysis
CFD simulation (Computational Fluid Dynamics) has established itself as an indispensable tool in modern engineering science. With the ability to analyse and visualize complex flow phenomena, CFD analysis enables engineers, such as simulation experts and designers, to make informed decisions about design and functionality.
Why use CFD simulation to simulate flows?
Flow analysis using CFD calculation is essential for evaluating the functionality of fluid-carrying or flow-around components. It not only provides a detailed insight into flow conditions, but also enables the flow properties to be modified and optimized in a short space of time. This not only saves time and costs compared to conventional test methods, but also promotes innovation and design excellence.
Cost savings
CFD simulations make it possible to virtually analyze the behaviour of flows without having to create expensive physical prototypes or carry out complex experiments. This can result in considerable cost savings in product development and process optimization.
Design improvement
Design improvement: CFD simulations allow engineers and designers to test and optimize different design options before creating physical prototypes. This helps to make products more efficient and powerful.
Increasing efficiency
In many industries, such as aerospace, automotive, power generation and building air conditioning, CFD simulations help to increase the efficiency of flow processes, save energy and reduce environmental impact.
Risk minimization
CFD simulations can be used to investigate the behavior of flows under extreme conditions without risk to people or the environment. This is particularly important in safety-critical applications such as nuclear power plants or aviation.
Product development and innovation
CFD enables companies to develop innovative solutions and respond more quickly to changing market conditions by speeding up the development process.
Improved process control
In the chemical industry and other process engineering sectors, CFD simulations help to optimize processes and predict reaction sequences, which can lead to higher product quality and productivity.
Understanding complex flow phenomena
CFD enables a detailed understanding of flow phenomena in complex systems that are difficult to capture experimentally. This is of great importance in research and development.
Environmental effects
CFD simulations can help to minimize the environmental impact of processes and products, for example by reducing the aerodynamic drag of vehicles or improving the efficiency of wind turbines.

Flow analysis (CFD simulation) – The areas of application
Automotive and aviation industry
Flow analysis plays an important role in the automotive and aircraft construction sector. The aerodynamic design of vehicles and aircraft can be optimized using CFD simulations in order to minimize air resistance and thus reduce fuel consumption. Comfort in the vehicle can also be improved by simulating the air flow in the interior.
Energy technology
In energy technology, CFD simulation is used to refine elements such as turbines and combustion chambers, whereby the simulation of heat transfer and combustion is central. In the field of renewable energies, especially wind power and hydrogen, CFD is also proving to be very valuable.
Medical technology
CFD simulations are also used in medical technology. For example, they can be used to simulate blood flows in arteries and veins in order to investigate the effects of diseases such as arteriosclerosis or to plan surgical interventions.
Environmental technology
In the field of environmental technology, CFD simulation can be used to simulate air flows in cities or to calculate the dispersion of pollutants in the atmosphere.
Construction industry
In the construction industry, CFD simulation can be used to optimize heating, ventilation and air conditioning (HVAC) systems in buildings. The simulation of wind loads on buildings or bridges is also a field of application.
Chemistry and process technology
In the field of chemistry and process technology, CFD simulation can be used to simulate and optimize chemical reactors or mixing processes in tanks and pipelines.
Marine and offshore technology
In marine and offshore engineering, CFD simulation is used to simulate water flows around ship or platform structures. This allows the hydrodynamic properties to be optimized and the efficiency of ships or offshore structures to be improved.

FEM: Frequently asked questions about Computational Fluid Dynamics (CFD)
CFD simulation stands for “Computational Fluid Dynamics Simulation” in English or “Computergestützte Strömungssimulation” in German.
It is a numerical method for investigating and analyzing the flow behavior of liquids or gases in various systems. These simulations are often used in fields such as aerodynamics, thermodynamics, fluid mechanics, chemical engineering, mechanical engineering and many others to understand and optimize the behavior of fluids in complex environments.
CFD simulations are also used in product development and process optimization, for example to improve the efficiency of flows in aircraft, automobiles, buildings, turbines, chemical reactors and many other applications.
CFD software (computational fluid dynamics software) is computer software used to carry out CFD simulations. CFD is a numerical method for analyzing and visualizing the flow behavior of liquids and gases in different environments. CFD software enables engineers, scientists and researchers to virtually model and solve complex flow problems without having to perform physical experiments.
Typically, CFD software offers the following features:
- Grid generation: The software enables the creation of a grid or network of discretization points in the space to be simulated. This grid is used to calculate the physical properties of the flow.
- Solution algorithms: CFD software contains special numerical algorithms and equation solvers to solve the Navier-Stokes equations and other relevant equations to describe fluid mechanics.
- Visualization: The software enables the visualization of the simulated flow results in the form of diagrams, animations and other representations to facilitate the understanding of the flow processes.
- Post-processing: CFD software allows users to analyze data from the simulations and extract relevant results to make decisions regarding the design or optimization of products or processes.
- User interface: Many CFD software tools offer a user-friendly interface that makes it easy for users to create simulations, set parameters and visualize results.
There are various commercial and open-source CFD software packages on the market, including ANSYS Fluent, COMSOL Multiphysics, OpenFOAM, Autodesk CFD and many others. Choosing the most suitable CFD software depends on the specific requirements of the project, the budget and the skills of the users.
