How would I adapt an existing mesh without adding cells in the z-direction? I have a one-cell thick geometry that I would like to adapt without changing the one-cell thickness (so x and y-directions only). However, everytime I adapt using a cell register or an expression, it cuts a line straight through the middle in the z-direction. How do I avoid this?

I want to adapt the surface (and internal cells) using a very fine background mesh. But even the background mesh is just one-cell thick so there's no reason extra nodes should be added in the z-direction of my un-adapted mesh.

Anisotropic adaption can be used to slice an inflation mesh parallel to the surface. If you're wanting to split in two directions only you'll need to remesh: adaption is designed to slice the cells in all three directions.
