Hello Everyone,
I am involved in simulation on venetian blinds (using mkillum for -ab 1). We are performing comparison for two sets of blinds, one is the normal conventional horizontal blinds and the other one is the split blinds in which the the blinds system is split into three equal parts. when measuring illuminance values for year long simulations . I observe that we get large errors in values in December varying from 10% to 60% ( difference in values between conventional and split blinds though they are at the same angle and same geometry) I observe these disturbances only in the month of December and at the sensor point closest to the window. Is this kind of error normal..?
Thank you

This may be a sampling issue. Look at a plan view of the workplane at the problem times -- it may be that the sensor is seeing direct sun in one case and not in the other. Even the tiniest change in geometry can result in a huge change in value if this is the case.
