Rotating domain issue
I am doing a transient case study on an airfoil, I made an interface between the rotating region and the static region. I carried out the analysis.
But the problem is the rotating domain is going out of its domain region. It is creating spaces between the interface as shown in attached pictures. I created a circular region of 0.6m around the airfoil. Then I created a C-shaped domain with another circle of 0.60001m.
Please suggest me what is the issue and why is it moving in such a manner.
