Hello dear researchers.
I want to solve a cylindrical waveguide, lick an ordinary standard optical fiber. I am familiar enough with the 2D-axis-symmetric model, but as I knew from the equations and output results (if I'm right) 2D-axis-symmetric models just solve the symmetric model in relation to the r=0 axis, and a simple revolve node, in the dataset, revolves the whole answer around the r=0 axis, and if the coordinate is not defined earlier, you may achieve only a revolved data where the data is multiplied by 2*pi.
Now, if I define a new coordinate system, particularly I mean it for electromagnetic waves, is it possible to introduce the 2D-axis-symmetric model to solve such vector-based problems properly???
Thank you in advance.
Dear Ghufran Alhadad , I think your answer is missed the main part when you were typing that. I'd appreciate it if you correct the answer.
Thank you, dear Markus M. Becker.
My concern is about the predefined physic modules and not the PDE. In the predefined modules, I didn't recognize any difference when I changed the coordination system (for example in ewfd module).
Dear Morteza
i want to understand why you want to simulate 2D cylindrical optical fiber using 2D axis symmetric?... you can easily simulate your fiber in 2D structure in comsol multiphysics. you must implement all the design to be inserted in the fiber parameters calculations such as effective mode area..etc.
