I am working with a system that has a user-defined DLL surface and want to obtain the settings. The ZOS-API recognizes that I am using a user-defined DLL but is not returning the correct file as defined in my code.

Is there a way to model and analyze a system using physical optics calculations instead of a ray trace?

I'm trying to optimize a system with a partner but our results keep coming back different from one another even though we are using the same operands and variables. Why is this happening?
