Software Developments and Tutorials

At Fraunhofer IWES, we developed extensions for OpenFOAM with the aim of automating the whole workflow and producing the best possible results. The use of OpenFOAM is not always straight-forward, which is why Fraunhofer IWES has provided a few tutorials to help interested users (also see the OpenFOAM Training and SOWE )

Extensions to other software have also been developed at Fraunhofer IWES.

Please follow the public links for codes and tutorials, which are available to all interested users:

• The case setup for the simulations of a DU 91-W2-250 airfoil can be found on Fraunhofer Gitlab webpage The airfoil is simulated at an angle of attack of 6.24° and a Reynolds number of one million. A fully-turbulent and a transition model can be used. In addition, an application for the automatic extraction of the pressure distribution is also included. Just run simpleFoam and compare the numerical results with the experimental values using the provided Gnuplot script afterwards (experimental values from Boorsma, Delft University of Technology, 2003). The code and tutorials are designed to work with OpenFOAM-4.
   

• An example of the simulation of the NREL phase VI turbine can be found on Fraunhofer Gitlab webpage. A fully-turbulent model is used and the simulation can be started with the Allrun script. A parallel computation is performed on 4 cores. The tutorial is designed to work with OpenFOAM-4.
   

• For the generation of airfoil meshes, we use the code construct2d which you can find on the Sourceforge webpage (external link) and have developed an improved version which can be found on Fraunhofer Gitlab webpage. It includes the possibility to generate fully structured O-topology grids around airfoils with blunt trailing edges and exports them to OpenFOAM as a blockMeshDict.
