Incident radiation mistake

hello everyone !
I am working on an incident radiation simulation with ladybug but it doesn’t seem to be correct since the most heated areas are in the north.
The grasshopper definition seems to be correct because it works with an other model and the sunpath is correct as well.
The model is a mesh created with kangaroo.

Could someone help me with this ? Sadly I can only attach one picture.
Thanks in advance :slight_smile:

Hi @cvb, welcome to the forum.

Have you checked the mesh is facing the correct direction (ie up?) - you might need to flip it


Hi Charlie,

Thanks for your answer.
What exactly do you mean by flipping ? I tried a flip matrix component after the mesh but nothing changed.
