Hi, I'm a new user to Comsol. I build a model to estimate the bending loss of a optical waveguide. It's a 3d model. but after I built it, the model doesn't work. It always pops up a dialog says "Undefined value found in the equation residual vector.", and "there is undefined value ..." I am very confused what is wrong with my model. I have uploaded my file. Hope you could help me with it. Thank you very much.
