IAM losses with IAM set to 1

[Karjalv]

Hi,

I just ran a simulation where I set the custom incidence angle modifier to be 1 at all angles, yet I still got 0.2 % IAM losses. Should it be exactly 0 %? Or are the IAM losses affected by some other parameters?

Thanks,

Vilppu

This should be 1 indeed. There may be some artefacts in the diffuse integral calculation, especially if you have additional shading effects.
