I have a problem that I feel must have a simple solution but I can't figure it out.

Basically, I want the mesh boundary to be perpendicular to the slope here. As you can see from the attached pictures the mesh boundary meets the exterior wall at 95.16 and 84.84 degrees (either side) but I need it to be 90 and 90.
Is there an easy fix to this?

Hi Euan,

Yes it is possible. But you need to realise that you have your angle "transition" between your vertical section and inclined one. You need to partition your geometry in order to force perpendicular element creation (see picture).

Add some edge sizing to specify the first layer height for instance. With this simple blocking you should be able to generate the mesh you want.

Have fun
