Hi all,
I am simulating a condition where I have an indoor farm with skylights. I want to find out how many photons will be received by the plants in one full day (lets say 22 March). There is a simple conversion between no. of photons and radiation received at the analysis point. I am using girdBasedSimulation with genCumSky.
I have a very basic question - Do I simulate with no. of bounces set to 1 or I keep my no. of bounces 4-6.
If I simulate with more than one bounce the cumulative radiation is more than the incoming radiation in the space, which makes sense because it is adding up from all the bounces. Logically the radiation energy in the room/space cannot be more than the total incoming radiation from the skylight.
I ran a simple box with one bounce and got logical results. The radiation in the box was slightly less than the incoming radiation. However I am confused why bounces should not be considered as the light will bounce and will have energy associated with it.
I hope I could explain the situation. Any expert advice on the physics and how to simulate it using ladybug-honeybee would be of great help.
Thanks and Regards
Saket
