Creating Geometries

The next step is to create a neat sphere object inside of our fluid domain. Therefore we change back to Object mode and press Shift + A. In the pop up menu we select Add → Mesh → Icosphere and set Subdivisions to 4 while leaving the radius at 1 BE (see Figure 4). The geometry is finished now and ready to be saved as a *.blend file

and on and on and then to:

Exporting to OpenFOAM®

The mesh is now finished and is ready for a final export to OpenFOAM® . From the menu bar we select Export → OpenFOAM® → OpenFOAM® (Grid only). We thereby create a case directory with the constant/polymesh folder, sadly marking the end of the main part of this tutorial.

enGrid also offers the export of complete case directories including solver settings. These have to be set up in the Solver tab of the Edit boundary conditions dialog. Afterwards we choose OpenFOAM® (Grid + solver parameters) from the export menu.
