Hey guys,

I am pretty new to Ansys ICEM and I am currently working on meshing a whole horizontal wind turbine (50 m radius) with tower and ground. At the end I want to compare Ansys CFX and OpenFOAM based on this mesh.

My plan is to have at the end a stationary far field domain with the tower and a rotating disk/domain for the rotor.

Up to now I managed to mesh the rotor disk (14 million cells, hex) with a sufficient quality. As the blocking of the rotor is a lot of work, I used the symmetry of the rotor to save some work. So I meshed only one third of the rotor and then copied the geometry and the blocking of one blade.

This worked so far, now I have the problem to include the far field and the tower. To use the symmetry of the rotor I first had to exclude the farfield (not symmetric like rotor) and the tower. Now after having the rotor blocked and I would like to "extend" my blocking to the whole domain, but I am not getting this done correctly. And I dont know if its possible anyway..

So my questions: Is it somehow possible to create the complete meshing in one ICEM project?

I attached some screenshots so that you guys know what I am talking about, the tower is not included yet. The size of the far field is also not final yet.

I would be very grateful if you could help me with my problem!

Thanks a lot in advance!
