edit mesh_GECO+Galapagos optimization

hi guys!

My attempt is to a volumetric optimization!

I'm trying to figure out how to edit a mesh by moving (by Galapagos) its points, that I got with the "decompose"command, according shadows and direct radiation (GECO information). In particular I would like to maintain a minimum volume in cubic meters and at the same time

-to minimize the shadows bring December 12 on the volume behind

-to maximize the surface hit by solar radiation.

Obviously before an optimization and then the other, in sequence. Probably what you get is a faceted volume. The thing I would check is similar to that of George, in the discussion below:

Thanks for the help that you give me!
