This might not be the right place to post this, but alas...I need to create an expression that allows me to refine the surface mesh on a specific wall boundary (titled "hole" in the image attached). I can do this by creating a boundary adapt marker. However, I also need an if statement to only flag cells on that boundary that are within a certain scalar range. You can make a field variable to do this, but it applies it to the entire mesh, and has no options to enforce it only on the boundary of interest. I think the only way to do this is to write an expression that basically says if both registers are satisfied. I have no idea how to write a statement to do this if it's possible. If I type in the name of my boundary expression (boundary_0), that works. But if I type boundary_) AND "field variable register name", that doesn't work. Any help as to how to accomplish this would be greatly appreciated.

In expressions, AND has to come before the operands. It is AND expr1 expr2 and not expr1 AND expr2. You cannot refine surface mesh because there is no surface mesh. Or may be you just stated it that way.
