I intend to run LB Incident Radiation using LB Analysis Period for a leap year, for instance 2020. I have modified component in the LB Analysis Period by adding a commond “leap_year=True” according to previous post. Sunpath for leap years - #2 by mostapha. However, I’m facing a error “1. Solution exception:init() got an unexpected keyword argument ‘leap_year_’”. Any idea to solve this issue? Thank you. Analysis period for leap year.gh (41.9 KB)
