I'm currently working on meshing a Circulation Control (CC) wing using a structured mesh to capture the boundary layer using ANSYS' Icem. Due to the wing blending in to the aircraft body, I'm using an O-grid to mesh the wing. The wing is unusual in that it has blowing ports, or slots, long its leading and trailing edges. First attached image is of the wing cross-section and while the second is a top down view. The third image shows the actual trailing edge ports on the model's wing. Hopefully this gives enough context for my question.

Now, the problem is I don't know how to create a clean mesh next to the ports. The forth and fifth image show what the mesh at the ports look like just using an O-grid. As you can see, there are a large number of skewed cells right at the port. (Please realize that the cell sizing and growth have not been correctly adjusted yet.)

I'm completely stumped. I have tried splitting some of the O-grid blocks to better model the ports but it just leads to an even larger number of skewed cells else where along the chord. I appreciate any and all suggestions, even if it means completely starting the mesh over. Thanks!

Edit: Just to be clear, in the screenshots, B.L. stands for "Boundary Layer" and U_infinity is the free stream velocity vector.
