Hello,
As far as I understand (I do not really use DIVA) it is not currently possible to use BSDF information in any Daylight Coefficient implementation (i.e. Daysim, DIVA). This is because of the method used within Radiance to perform the Daylight Coefficients calculations... something I do not really fully understand.
I have read things that make me think that "they" are working on an implementation of the 5phase method that should enable using BSDF within DIVA/Daysim... I am just gossiping, though.
As I mentioned before, I do not really use any of those programs (I usually use pure Radiance), but this is what I understand from the methods underneath.
Regarding any other options, Radiance or OpenStudio 3phase method allow using BSDF information, but I would not advice that if your BSDF is very specular.
Bye!
