Radiation on a dome

Hi all
I have 2 shape. a complex dome and a cube
I cant calculate radiation on one of them. radiation on complex dome is 0. however i have result on the cube. one time i just set dome and another time just set cube.(one set a brep)
I didn’t set a context geometry in the both modes.
I changed my grid size and my epw file but didn’t happen a new result except 0.
I don’t know why my result is 0. maybe my shape is complex??
