Olivier Dambron replied to Mustafa Teksoy's discussion Solution flag is not valid. To initialize octopus, please set up a valid configuration. in the group Octopus
"Hi Mustafa,In case you have already found solutions when you pause, you could reinstate one and start again with presets.Another trick, a bit rough though, would be to keep a copy of the gene pool at the state which is flagged 'True' so…"

Olivier Dambron replied to Theodoros Galanos's discussion Butterfly and HumanUI: an outdoor CFD example in the group Ladybug + Honeybee
"Mostapha and Theodoros,Many thanks for helping.I have figured out how to use grading to generate denser mesh where needed. Very Useful!2D cases are convenient, I will post some results of optimisations. On the thermal end:Although Butterfly is…"

"Hi Theodore,Thank you for your previous reply. Please forgive me the silence as it took me a while before pursuing back my CFD journey.I have been using the outdoor example file to run airflow through an atrium with windward windows opened. I…"

Olivier Dambron replied to Timothy L's discussion Each Iteration adds to RAM Usage - Honeybee in the group Ladybug + Honeybee
"Hi Mostapha, I am facing the same type of issue with a recursive voxel aggregation. Within a loop of Anemone I use honeybee to test recursive geometries. with the 40 000 points, and therefore voxels to be tested, my memory runs out quick and rhino…"

Olivier Dambron replied to Saeed's discussion Running Octopus Problem in the group Octopus
"Hi Saeed, In the grasshopper component folder make sure the files for octopus are unblocked. Click right and tick unblock. Close rhino and gh and reopen. Let us know Olivier"

Olivier Dambron replied to Boris Plotnikov's discussion New Solar Envelope Component now available in the group Ladybug + Honeybee
"Thank you for this great tool.If I understand correctly, the method here relies on geometrical dependencies with the Sun Vectors.Could it be applied with dependencies to simulation results such as the VSC component? Olivier"

Voxel, loops and culling.

I'll try to explain as clearly as possible.Please let me know if you can help me out with rhinoscript python to automate grasshopper. Selecting the first of the 18 points.From the selected point is made a box. The box(n) is put into a datatree "sampleMass". I test sampleMass through a type of simulation. The test returns TRUE.…See More

"Hi Mostapha,thank you.I have clustered my geometry entirely defined in GH and will try to run it.I have attached the file here, could you have a quick look at the settings? It seems there are 2 rectangles within the wind tunnel.Olivier"

Mostapha Sadeghipour Roudsari replied to Olivier Dambron's discussion Tropical Glare in the group Ladybug + Honeybee
"Olivier, In cases such as yours you can use a combination of simple analysis. If the sky is mostly cloudy, then daylight factor analysis should give you a good idea of potential enough daylight inside the space. For analyzing the glare probability…"

"Hi Theodore, Thank you very much for all this. I have run your grasshopper definition.  This was the first error I encountered. I then bypassed the humanUI by using boolean toggles into the 'runit' inputs of the rest of the…"

Sarith Subramaniam replied to Olivier Dambron's discussion Tropical Glare in the group Ladybug + Honeybee
"Hi Olivier, Since Daysim (the annual daylighting simulation engine used by HB) employs data extracted from tmy epw files for daylighting calculations, I think it is safe to assume that the sky conditions are probably reflective of the prevailing…"
