Arbitrary Rotating Inlet ACMI
The arbitrary coupled mesh interface (ACMI) condition is compelling if the usage of the boundary condition is well understood. The following training case builts an ACMI for a rotating inlet pipe which is connected to a larger second pipe. The set-up is tricky and needs advanced techniques and applications for the correct ACMI generation.
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 50 % possible.
Creation of an Arbitrary Mesh Interface (AMI)
The generation of the arbitrary mesh interface (AMI) boundary condition is used for splitting the static and dynamic mesh regions. To create such boundaries, different methods can be applied. Commonly, Holzmann CFD uses the inhouse mesher of OpenFOAM namely snappyHexMesh, to generate high valuable numerical meshes. Discount of 50% 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 50% possible.
Arbitrary Rotating AMI
Dynamic meshes are state of the art for engineering processes. In many cases, the numerical analysis has to be adapted to the rotation because, e.g., the multi-reference-frame (MRF) assumption does not hold anymore. To investigate into such phenomenon, OpenFOAM offers a mapping and interpolation boundary condition namely arbitrary mesh interface (AMI). Discount of 50% possible.
ACMI Boundary With Heat Transfer
In industries such as the steel produces, molds are vibrating while they cool the moving liquid pool. Such a phenomenon is exciting and has to be considered in the numerical analysis. There is a wide range of application that combines heat transfer and moving parts. Therefore, these training case demonstrates how to set-up the ACMI boundary condition correctly.

Arbitrary Water Pumpe
Simplifications are used in computational fluid dynamics applications almost in every scenario. In most cases, special regions are not of main interest. An example is given in the following training case, in which a water pump (which is just generating a pressure drop) is removed and replaced by a 1D cyclic boundary condition. The simplification leads to less numerical cells and therefore a reduction of computational costs. Discount of 50% 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.

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 50% possible.

In a wide range of engineering applications, the buoyancy force is the main driving force for the fluid flow. However, in the case of numerical investigations, engineers do have problems in setting up such cases or run into troubles/crashes with OpenFOAM®. This training case shows the set-up and geometry preparation of a more complex application. Discount of 50% possible.
Gin Tonic (Conjugated Heat Transfer)
Heat transfer problems, including several different regions, are state of the art simulations for CFD engineers. In each engineering application, heat transfer processes occur. Depending on the investigation, the energy transport can be one of the critical quantities such as thermal stress, temperature resistance and so on. The training case provides the correct set-up for such kind of problems and will guide the trainee through the different steps. Discount of 50% 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 50% possible.
Teslas One-Way-Valve Optimization | OpenFOAM® and DAKOTA®
Nowadays a wide range of applications needs to be evaluated for a working point and therefore be designed for optimal operation. Analysis of different designs or flow parameters can be an intensive work while the data analysis is not easy. To reduce manual labor, highly advanced optimization methods - implemented in DAKOTA® - can be used in combination with OpenFOAM®. This training case shows how to couple both software tools, DAKOTA® and OpenFOAM®. Discount of 50% 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 50% possible.
