— pimpleFoam, dynamic mesh, six degree of freedom, flow-induced rotation —
As the flow-induced rotation is a unique and high interesting topic, Tobias created a new training case. Here, an anemometer of type F460 was investigated. The test case is based on a publication that is included in the tar file. The »dynamicMeshDict« includes a lot of comments to introduce one to the different keywords that are needed for the set-up. However, it is worth mentioning that the rotor is starting to rotate based on the fluid flow, but Tobias never ran the case completely. As it is a 3D model, including tiny numerical cells, the calculation time is too long on Tobias' old computer. However, as the case was already created, it is worth to share it with the community.
— After four days of numerical analysis, Tobias stopped the calculation —
The case set-up, especially the inertia matrix and the values used in the »dynamicMeshDict« are derived from the CAD software Salome®. The case is identical to the »Vertical Axial Wind Turbine« tutorial except that one is investigating into a 3D model. Please do not hesitate, if you think the set-up of the case is wrong or if there is a better solution of analyzing flow-induced rotation regarding the numerical point of view. However, the case shows one how to set-up the arbitrary mesh interface AMI and how the six-degree-of-freedom (6-DoF) is used.

gThe available training cases are tested and built for different OpenFOAM® versions. During the tests, only the OpenFOAM Foundation version of OpenFOAM® was used. Furthermore, the following software packages are required for most of the training cases: Salome®, ParaView®, and for optimization tasks one also needs DAKOTA®. The cases might work with the ESI version of OpenFOAM® too (not tested). Additionally, there is no support for Windows-based OpenFOAM® versions.
