I have used ANSYS Meshing and created a multibody body part as I want a conformal mesh.

The multibody part has resulted in extra walls appearing for the boundary conditions in FLUENT. The default settings for these are no-slip walls.

I am not sure exactly where these walls are so I ran a simulation and tried to plot a contour on the walls however FLUENT came up with a message stating cannot plot on sliding interface.

I have plotted velocity and pressure contours on the planes I created which ran down the centre of the fluid domain and nothing strange appears to be happening i.e. the fluid hitting a wall the interface of the parts of the multibody.

If anyone can shed any light on this it would be much appreciated.

Upload some images and elaborate using that to have some idea of your problem.
