Hi Leonid,

Getting this value from a Merit Function operand is handy. Provided you are ok to save your settings for the POP analysis feature beforehand (see the Help File about POPD).

You can use GetOperandValue, which returns the value of a Merit Function operand without needing it in the actual Merit Function Editor:

surface = 0 # Saved ending surface


wavelength = 0 # Saved wavelength


field = 0 # Saved field


data = 0 # Total fiber coupling


Total_fiber_coupling = TheSystem.MFE.GetOperandValue(ZOSAPI.Editors.MFE.MeritOperandType.POPD,


                                                     surface, wavelength, field, data, 0, 0, 0, 0)


print(Total_fiber_coupling)

Something like the above should work in a Python Interactive Extension, or Standalone Application. Change the data variable to whatever is most relevant to you.

Let me know if this works for you. Or if you need help setting up the whole POP analysis through the ZOS-API.

Take care,

David

Hi David,

Thanks! It works!

Hi Leonid,

No problem, don't hesitate to mark my response as the answer to your question such that other people in the future can refer to it.

Take care,
