I’ve been trying to analyze the illuminance received in a room as seen in the attached picture. Four rectangles and a skylight was supposed to be the apertures. I have tried PIT Grid Sensor and PIT View Based. I have also set the appropriate radiance parameter. However, the apertures are not considered in the analysis and the result always shown zero (0) illuminance. Any solution to this problem?
@Aliarch thank you for pointing that out. I have checked the Cplane in rhino and it is normal. I checked the model in the Grasshopper and somehow it is flipped (the X and Y axis are changed). I have re-adjusted it and retried the simulation, but the result remains 0.
I read somewhere that the sensors might be facing down, but in the GridRooms component there’s not any sensor direction variable.
If the normal is OK, try to set the grid offset to something higher than the floor. It might be that the floor and the grid overlap so the floor is “hiding” the grid to get light.
The best is to upload the model.
