The Surface Feature Refinement (SFR)
SnappyHexMesh can refine defined feature edges during the refinement stage. However, many people in the community have a lot of problems with the feature edge refinement strategy. Therefore, Holzmann CFD provides the SFR case which meshes a pipe with three different surface feature refinement set-up's. The results, especially the wrong ones, might be familiar.
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.
