Normalization of Grid-function on a single region

Normalization of Grid-function on a single region was created by ajf367
Hello,
I'm trying to figure out the "best" way to normalize a resulting grid function on a subsection of the mesh. For the purposes of this topic I'm considering an Eigenvalue-Problem similar to 1.7.1 in the tutorial ( docu.ngsolve.org/nightly/i-tutorials/uni...7-helmholtz/pml.html ).
The geometry is as follows:
I've modified the Arnoldi solver to output only the eigenvalue I want and have the resulting gridfunction u associated with it. However, I want to normalize u only on region 1.
Do I need to define a new mesh that only covers region 1 to integrate it or is there a way to restrict the integral only to the first region?
Thanks,
AJ

Code:
geo = SplineGeometry()
geo.AddCircle( (0.0, 0.0), r=1.0, leftdomain=1, rightdomain=2, bc = "scatterer")
geo.AddCircle ( (0.0, 0.0), r=2.0, leftdomain=2, rightdomain=3)
geo.AddCircle ( (0.0, 0.0), r=3.0, leftdomain=3, rightdomain=0,bc = "dir")
I've modified the Arnoldi solver to output only the eigenvalue I want and have the resulting gridfunction u associated with it. However, I want to normalize u only on region 1.
