Diffuse and beam radiation

hi all
in the below pic, if I set ‘true’ diffuse radiation, my results are direct radiation on my geometry? my geometry is a semi-sphere!
I don’t know why annual diffuse is more than direct radiation?!! it is so strange! EPW… LONDON

actually, I have a semi-sphere and I going to calculate how much radiation will be received by my geometry in a year, then I going to compare annual diffuse radiation and annual beam radiation in a year period.

Hi,@ahad As the picture showed,the value of grid size is 0. This setting maybe get the wrong result.
