One way to solve this would be to keep two separate meshes, one to hold the
initial boundary values and another to keep the refined mesh. So each step i
would make an interpolation on the first one to get boundary values for the
new nodes created at the refined mesh.
In that case, you can also just interpolate onto the original (coarse) mesh
and transfer that interpolated function to the new mesh via SolutionTransfer.
This is cheaper to use later on (because it doesn't need interpolation between
meshes) and you won't have to keep two meshes around.
