Moving Non-Confromal Interface
 

Hello,

I would like to move a body through the domain. The domain is divided into two zones: A boundary layer zone extracted by prism cells and a fluid zone consisting of tetrahedra cells. Both zones are created with tgrid. The surrounding interior wall of the prism boundary layer exists of tri and quad elemets. Consequently, there are interfaces built up between the two zones and connected to the two zones.

If the body starts moving the boundary layer and tits connected interfaces are following the motion by smoothing. However, the interfaces connected to the fluid zone do not move and , finally, negative volumes are the result.

Is there any possibility to tie interfaces or has someone a good idea?

Thanks for reply! Cheers Bastian
