This is achieved using the daysim ds_shortterm sub promgram (http://daysim.ning.com/page/daysim-subprogram-ds-shortterm-1).
Is it possible to use this via Honeybee?…
tween 3 different types of sky for Ladybug and also Radiance and the difference is less than 5%.
2. Ladybug is using gendaymtx to generate the sky. You can read the details here: http://www.radiance-online.org/learning/documentation/manual-pages/pdfs/gendaymtx.pdf
3. You can use Daysim subprogram ds_shortterm to generate the sky for less than and hour timesteps (http://daysim.ning.com/page/daysim-subprogram-ds-shortterm-1) but then the number of patches will be limited to 145 patches. It is not applied to Honeybee.
4. Sky is almost 0 on the top because of the bug that you found. The value for the last row of patches was missing from the code. It should be fixed now.

Ok, sounds to me then like that PATH variable was not set correctly, and the reinstall fixed that. In theory, I don't think DS 3 vs 4 should make a difference.

orm Surface Surface, I am able to create wire frame and mesh without any problems. However, the elements/cells have variable size which I do not like. So I starting playing around with uniform DS. To this end, I have a few questions:
1. Using uniformal DS on a symetrical airfoil I do not get a symmetrical mesh/wireframe (see picture)
2. While the wireframe seems to be correct, the mesh does not render everywhere (see picture). Any ideas why the mesh does not appear in select places?
3. Does anyone have any ideas on how to combine a uniform DS with a conformal boundary layer i.e. connect the open ended wires of the uniform DS according to the geometry.
I attached some pictures and the grasshopper/rhino files for reference.
Thanks for the help in advance!…
he results.
Chris is correct about why values are calculated at .5 hour and not the start of the hour. The timestep is still hourly though.
Finally, Daysim is capable of generating the results for timesteps less than an hour (http://daysim.ning.com/page/daysim-subprogram-ds-shortterm-1). We are not currently exposing it in Honeybee though.…
