"Hi David, Thank you very much for your quick reply and now I have a better understanding of how Galapagos works. I read one of your earlier comments on dynamic sliders with constructing a domain and it did turn out that the correspondent unique…"

David Rutten replied to Weishun Xu's discussion Dynamic Input Silder for Galapagos?
"1. Dependent sliders oughtn't matter all that much.  2. I don't think so. Instead of integer sliders from 0 to m-1, you could set up floating point sliders from a to m-1, and then remap that number to an index, but then you'd…"

Dynamic Input Silder for Galapagos?

Hi Grasshopper community, I have a matrix of planar grid points and I am selecting two different points from them as corner points to make a rectangle. Then I need to do some optimization for the best rectangle choice. Supposedly I have m columns and n rows of points, and my first selection is a,b where 0<=a< m-1 and 0<= b< n-1, then the range of my second point c,d should be a < c <=m-1 and b < d <= n-1 I want to set up integer abcd as four independent sliders for…See More

Is it possible to simulate luminance level for a certain hour?

Hi All,I am trying to run a design optimization that is centered on luminance level of a certain hour in a year. I know I can run the annual simulation through Radiance and use Honeybee Read Hourly Results to load hourly data, but since I have more than 80,000 design options to run through this might take too long. Would it be possible just to get data of a certain hour without running the annual simulation?Or, if Ladybug radiation analysis doesn't consider reflection, is there some open…See More

"You need to set useOldRes to False. There are a number of discussions on this topic in the group. I suggest to take a look at them."

Cumulative Sky won't generate?

Hi Friends. I'm new to Ladybug and I have been having trouble with radiation simulation. I installed Radiance and manually copied the gendaymtx.exe file to my working directory folder. My problem is that Gendaymtx only runs for a split of a second and it doesn't seem to be generating the sky data needed (I also switched off the useOldRes toggle to make sure it runs every time). I'm getting KeyError from the SelectSky component and the sky visualization is completely blank. I used epw data from…See More
