I figured that out after posting this. Did it using the conformal mapping. Thanks for your reply though. I actually found one of your old posts with some sample files.:)
On a related note, when I am using the OptiFiber to get the Macrobend losses for the POF, it is not showing me any results for the required wavelength and fiber. Attaching the file for reference.
P.S: Not sure if it is ok to post this in BPM forum, but as you used OptiFiber in your example, I suppose you are the right person to ask.
