Hi guys

I am simulating a 3D rotating airfoil. I have created two separate zones 1- stationary zone (external zone) 2- rotating zone (internal zone). then an unstructured mesh was defined. but the problem is that, after simulation, the two zones penetrate each other. is there anybody here, who can help me?

thanks

Hello What do you mean by: "the two zones penetrate each other"? Can you clarify?

Hello
Dear Kremella

According to figure, the rotating zone has penetrate the stationary zone and it has caused an empty surface created ( white surface near the airfoil).

Did you create the mesh using Fluent Meshing or Ansys Meshing? Did you try to preview the mesh motion to confirm that the nodes at the stationary interface do not move along with the nodes at the moving interface?

What is the centre of rotation of the fluid volume? What is set in the cell zone panel?
Also check the boundary conditions at the top & bottom of the domain as the contour suggests you missed something.
