Dear Tommie,
Unfortunately, we don’t have the time to check your analysis and the Mathematica file. I would assure you that OptiFiber software is being used by many fiber manufacturers over the world for long time, one example is Corning.
Please email me (ahmad.atieh@optiwave.com) your contact information & your institution and we’ll check if your institution has valid maintenance and support license to allocate some time to look into your analysis.
Regards,
Ahmad
