Assuming z is along the wing "axis" ie is into the page then I'd use sliding or deforming mesh depending on what you're after. With the holes in the image, you need to be careful with the 2d assumption, but you also need to decide what's underneath the holes. Ie does that section cover a cut out? If so, you need that in the model too: we're modelling all of the fluid zone(s).
