Increasing product efficiency, reducing costs.

Solutions for your challenges.

Flow simulation:

combustion and flow solutions offers incomparably precise analyses from which concrete optimizations of your components emerge. This is achieved by CFD simulations for various flow types. These include laminar and turbulent flows, multiphase flows, compressible flows and flows with free surfaces.

Thermodynamic simulation:

Products are only truly efficient if they are performing under all possible environmental conditions. To this end, combustion and flow solutions also offers simulations for thermodynamic processes, including heat transfer, combustion and cooling systems.

It only takes 8 process steps

01 geometry
02 volume
03 mesh generation
04 define physics
05 boundary conditions

06 simulation
07 analysis
08 innovation


As a first step your CAD model ist getting imported. Here, the flow geometry is modeled and the model is optimized for the simulation. The geometry is closed, overlaps are removed and components are positioned cleanly in relation to each other.


For a CFD calculation the negative image is needed. By extracting the inner volume, the fluid is represented as a separate component for later meshing.

mesh generation

The accuracy and speed of the simulation strongly depends on the quality of the mesh. For this purpose, we develop fine "meshes" that resolve local flow effects and turbulence.  

define physics

Depending on the task, different physical models are used. The correct selection of the models and the corresponding parameters is crucial.

initial and boundary conditions

The initial and boundary conditions define the operating state of the component or system. All conditions must be specified as accurately as possible, provided they are known. Otherwise, estimates from many years of CFD simulations are used.


At this point the actual calculation of the flow, heat distribution, combustion, emissions and other factors takes place. The computation time depends on the number of CPU cores used, the complexity of the physics and the size of the model.


In this process step, the 3D representation of the results takes place. Streamlines, sectional planes, surfaces and much more can be displayed. This results in the "optical access" into the interior of the physical processes. The presentation of the results finally leads to the basis for improvement suggestions of your component.


After a successful analysis, the next part of the process starts seamlessly: The redefinition and execution of improvement proposals. These are made possible, for example, by adapting the geometry or the operating condition.
