Fiber to Waveguide

Please login with a confirmed email address before reporting spam

Hi I am having trouble figuring out how to couple a fiber optic to a waveguide. I keep getting an error of having an undefined value in a residual vector and I don't know how to resolve it. I have attached my model. Any advice will be welcome!
