compute efficiency map using macro and compose script

Dear Sir/Madam,

I tied to compute efficiency map of the IPM by combining Flux CreateLookUpTableFromTMProjectDQLight macro with Efficiency_maps Compose script in Flux 2D 2021.2. In the "represent_maps.oml" script, the code required an Iron losses at maximum speed, but I could compute it at nominal speed and current. How do I calculate this? 

Another question is why are Joule losses on the magnets and windings of the stator not included in the script to calculate the efficiency with high accuracy?

Thank you for your help.
