Ladybug Incorrect Sunlight Analysis

[Krim]

Hi Everyone,

I am encountering this error in Ladybug, where I see the sunlight analysis in 4 quadrants, with 2 of them having 0 sunlight hours. I have tried changing the offset distance and grid size, but I get the same result. I am only analyzing the first 2 days of january, and the image attached below shows my context - the buildings highlighted in green, and the target geometry which is the ground mesh.

I have attached a onedrive link to both my rhino and grasshopper file, could someone please help me with this.

Is the ground surface a mesh? The grid size won’t change mesh inputs. Try to use a Brep geometry.

If it is already a Brep, then make sure you’re using the correct units so the grid size generates the expected results.

Thanks, it was the number of mesh faces I think.
