Define fitness number in Galapagos

Hi Everyone:

I have a question concerning defining the fitness number in Galapagos. I'm using DIVA-for-GH and Galapagos to optimize the shading device. I'm doing the rendering of the view and need glare analysis to see the efficiency of the shading device; however, since DIVA-for-GH only offers the rendering option, I need to calculate glare index after. The software evelglare (http://www.ise.fraunhofer.de/de/geschaeftsfelder/energieeffiziente-...) can do glare analysis. I'm wondering if there's a way to use evelglare to calculate DGP number as the fitness in Galapagos?

Thanks
