In the computational fluid dynamic analysis, engineers are using a fixed rotation set-up for the moving mesh that includes the design of the turbine. However, if one is interested in a flow-induced rotation, the six degrees of freedom library in OpenFOAM can be used to handle such analysis. Discount of 25% possible.
Generation of an 2D arbitrary mesh interface (AMI)
Holzmann CFD offers a wide range of different tutorials. Especially focused on dynamic meshes and special features. This training case provides all information that are required to generate a 2D arbitrary mesh interface (AMI) in OpenFOAM. As always, the case uses the well-known and clean bash scripts. Discount of 25 % possible.
Arbitrary Coupled Mesh Interface
In engineering applications, it is common to have active parts which connect and disconnect. Using the arbitrary coupled mesh interface in OpenFOAM® allows one to use dynamic elements that connect and disconnect during the time. The usage of such boundary conditions and the correct set-up is the principal focus of this training case. Discount of 25 % possible.
Polluted air is a problem of many countries especially in big cities or at landscapes in which the air exchange is small related to the geographical location. Thus, governments make laws such as TA-Luft, BImSchV in Germany or stringent global regulation (world bank). To reduce the pollution of engines or any operating system consuming fossil fuels numerical analysis methods can be used to perform optimization to the existing systems to run more efficient and effective and therefore economically better.

Geometric Variation Optimization | OpenFOAM® and DAKOTA®
Optimization tasks are the state of the art to optimize the design for the operating point. To prevent different modeling scenarios manually, the free software tool DAKOTA® can be used to automize the optimization task. This training case shows the coupling of both software tools, DAKOTA®, and OpenFOAM®. Discount of 25 % possible.
Everybody is aware of a windscreen washer build in a car. However, most of the people think that there is a nozzle which is distributing the water onto the windscreen. This training case demonstrates the proper work of such a device. It is not a nozzle nor a mechanically driven spray generation. By using deliberate geometric designs, a fluid induced instability is generated which distributes the outcoming water stream periodically onto the object it is aimed. Discount of 25 % possible.
Vertical Axial Wind Turbine (VAWT)
Flow-induced rotations are state of the art problematics in computational fluid dynamics analysis such as wind turbines or Kaplan turbines. OpenFOAM® offers the possibility to use an existing library namely the Six Degree of Freedom (6DoF) library to model such a phenomenon. This training case will guide you through the necessary steps to simulate flow-induced rotations. The well known and structured Holzmann CFD's run script is generating the whole case automatically and therefore, you can understand and follow each step. Discount of 25 % possible.
