Geco and Galapagos Surface Manipulation

Hi,

I'm trying to manipulate a mesh using galapagos and geco, based on maximising solar access. When running the galapagos plug-in, I can see the form moving in Ecotect, but no values are registered in the solver and the surface remains one constant colour.

I am new to all these things and think I'm missing something with galapagos. 

Would really appreciate any help.

Thanks

Carly
