Integral of value over different internal geometries

Please login with a confirmed email address before reporting spam

Hello,

I've currently got a model where I'm looking at the fundamentdal mode profile of light through a waveguide. There's a parameter sweep of the waveguide width. I want to take the integral of the x component of the magetic field of one parameter solution multiplied by the conjugate of that for another solution. For this I am using this expression :

intop1(withsol('sol2',emw.Ex,setind(Wwg,1)) * conj(withsol('sol2',emw.Ex,setind(Wwg,2))))

in a global evaluation node and intop1 defined over all domains. However for this I need to define a dataset in the global evaluation node. Defining it as either one of the parameter solutions used in the integral calculation gives me slighty different results, so I am unsure of how exactly to compute this correctly.

Any help is appreciated.
