Hello everybody,

I am working on a 2D simulation of a vertical axis wind turbine. My flow domain consists of a large rectangular domain representing the surrounding air of the turbine and the turbine geometry which is located in a circular domain in the center of the large domain. I want the turbine to rotate by using a sliding mesh between both flow domains.

So far, I imported my geometry in DesignModeler and prepared it to get two seperate surfaces and assigned named selections to inlet, outlet, walls etc. I also created/named one interface at the stationary domain around the turbine and one interface to the rotating part.
Now, I want to create the mesh with Fluent-Meshing 2D Meshing Workflow but am getting the error, that "More than one meshing part is identified. Perform share Topology in geometry and try again."

I have already done that Share Topology once and was successful in creating the mesh. But in Fluent solver, I wasn't able to create a mesh interface. In the boundaries section, Fluent created a combination of my two interfaces and an additional shadow-version of this combination, both assigned as walls without the option to change to interface.

Is it possible to create a 2D mesh in Fluent-Meshing without the Shared Topology to keep the interfaces created previously?
Hope, there is any chance out there to get it done this way.
Thanks,

Lennard
