You are welcome!

Thank you!

Not sure. Did setup the Bluecfd environment? Are you running Rhino in admin mode? Did you run a calculation successfully before?

@@PhilippGalvanDesign yes like your video, but I didn't wait for the calculation as it took so long and it was running and running and I didn't know when will it finish.

Not that I know at least not in Butterfly. What you like to analyze?

@@PhilippGalvanDesignwind flow

@@PhilippGalvanDesign yes

Butterfly can only analyze one wind direction at a time... Although you could more than one inflow but that would not simulate a cyclone. Butterfly works like a physical wind tunnel. Maybe you need to modify your question. Instead of wanting to simulate a cyclone which is pretty unpredictable maybe think of what problem you want to solve first.

Hmm not sure. Haven't encountered such problem. Let me know if the problem persists.

@@PhilippGalvanDesign thanks for replying. yes unfortunately it continious. I shared the post in ladybug tools dicourse platform under the name in oyongoren. I'm trying to try every suggestions 🙏

You might need to check the mesh resolution of the objects. Maybe you need to send me a screenshot if the problem persists...just note that I'm traveling at the moment and won't be home before in 2 weeks.

@@PhilippGalvanDesign Thanks a lot for your reply Have a great travel 🤗

@@ClintWorton you are welcome

I use Landsdesign. Rhinolands is basically a combo. Rhino + Landsdesign. In case you don't have Rhino you could go for that option. it doesn't have more functionality...

No specific benefits. It's for me to survive as a channel and I will prioritise members questions and suggestions.

12:59 here the problem occurs while toggle set to true

please help me its important

Did you follow the installation properly. Which version of bluecore CFD did you install? Did you follow the steps to setup the bluecore CFD environment. And are you running Rhino in admin mode?

I'm not sure I haven't looked into HB for a while. I'll check it out when I get to. Is the the 'HB read room comfort result's part of HB radiance or HB energy? Also is your shading inside or outside the glancing line?

You might need to check if your surface is not upside down. Or you maybe have a different colour legend code. What is the temperature under the canopy and what is it next to it? Are your canopies solids? Which climate are you testing? (Which geographic location) Which time of the day are you testing?

@@PhilippGalvanDesign Turns out I was testing for 7 pm in a climate where the sun had set, so this would makes sense. Is there a way for calculating WBGT as opposed to UTCI?

No you don't need to extrude them into solids. Except if you use Honeybee.

@@nanox4520 Not necessary except you want to run Dragonfly models through E-Plus... I never used it as it is very specific.

The comfort map is the perceived temperature. But for PV panels the most important aspect is the exposure to the sun. Not the temperature. But you should be able to calculate a heat map just from the surface temperature only. It's an interesting topic.i might make a video.on this.

I am wondering if you need a 10 minute interval for a Sun Hour study. The idea is to calculate hours together. Except you want to animate the Sun exposure over time. However I think the reason why you get a seventh step has something to do with the way how ladybug calculates this. It adds values for points in time. So for example. The first value is captured at 12:OO then 12:10, 12:20, 12:30, 12:40, 12:50. (6 values) Now because you define the hour as 12:00 to 1:00 you get a seventh value at 1:00. This value supposed to be part of the next hour. 1:00, 1:10 1:20 etc... Now again I don't see much reason why I would calculate an hour in 10 minute interval if I can just calculate 1 hour with an hour interval... You get the same result...

In theory I should be possible but I haven't tried that myself. I am quite busy these days. But if I come across it I'll try

Which version of rhino are you using. And which blue core CFD version did you install?

@@PhilippGalvanDesign same version 2017 bluecfd and rhino 7

Are you running Rhino in admin mode?

And did you create the CFD environment?

@@PhilippGalvanDesign how can i check thz ?

Is this a question?

Yes good idea, I will do a follow up video at some point to explain use cases.

Question 1: The human to sky relationship doesn't require weather data information. It's the relationship between location and objects. No sun movement. Result is one number per point. Question 2: you need to average the list of values per point to get an average number per point. Then you need to flatten the resulting list to get a single list with one value per point. Not a list of lists with one value....

@@PhilippGalvanDesign Thank you a lot for your reply.

Yes I'm using the probe points as my points for the human to sky relationship component... In the UTCI component I input the windspeed resulting from Butterfly. Not sure if I can follow your questions correctly.

Daylight is different from Sunlight. With Solar analysis you can calculate the direct sun hours which doesn't include the skylight. Only direct light. Have you tried the solar radiation study in Ladybug or the Sun Hour study?

@@PhilippGalvanDesign Thank you so much for your answer. I did solar radiation in Lady Bug

You might want to look at the Sun envelope in the new Ladybug 1.8. that might be able to do that.

Or at least help to get there.

@@PhilippGalvanDesign Thanks for the instruction!

@@abdoudoula2472 Which Openstudio and radiance version did you install?

@@PhilippGalvanDesign open studion 3.8.0 and radiance 5.4 .... thinks for responding me

@@abdoudoula2472 First you need to install the right 3rd party versions for 1.8. Also I would make sure 1.5 is completely uninstalled before installing Ladybug 1.8. Then instead of installing open studio. Uninstall and install the open studio app. Which includes the right version of open studio and Energy Plus. Follow this guide and links for the right versions: github.com/ladybug-tools/lbt-grasshopper/wiki/1.4-Compatibility-Matrix

@@PhilippGalvanDesign what do you meen by the right 3rd party version for 1.8 .... the 3rd party of what now i'm using rhino 7.37.24107 and if i follow the guid in the link i'dont matche betwin ladybug 1.8 and rhino 7 because ladybug 1.8 need rhino 8.4 ..... what should i do bro

@@abdoudoula2472 Openstudio, and radiance are 3rd party software which you need for These tutorials.

@@galjvdjy you have to do what you have to do.

Now that I figure out , I made a new folder to save my epw file :) but import epw showing an error - index out of range :2 , I don’t know what does it mean .

Ok you don't need to download the weather data. You can just place the URL of the weather data in a panel. Ladybug will do the rest for you... Now if you got an error on your weather data then it might be corrupt. Some weather data files are empty I realized. If the size is very small it might be empty. Have you tried a different one?

Dear Philipp, Thank you for your response. I re-watched the tutorial carefully and managed to input everything correctly. However, I am unable to see the desired results because the software freezes every time I connect my surfaces via brep. I also realized that the Radiance file is missing. I am currently trying to install Radiance, as I am doing thermal comfort analysis using materials as well. If I encounter further problems, I will ask for help. If you have any suggestions, please let me know. Thank you.

Make sure you install the right versions github.com/ladybug-tools/lbt-grasshopper/wiki/1.4-Compatibility-Matrix

Further be sure your file units are in meter not millimeter. Often a reason why things freeze.

🤣🤣🤣

Not sure really. Hard to know without looking at the script or model. I would probably test more. And different settings, makeing sure no other settings have changed.

Glad you think so!

Thank you

There is only one version from 2018. Sadly the developers haven't updated this software.

@@PhilippGalvanDesign but can i use it or no?

Yes you should be able to use it still. I use it together with Rhino7. I haven't tried it with Rhino8. But I don't think it's an issue.

Ha ha, thanks!

I played with the environment to allow for both sun and skylight. Which gives a more realistic look. The menu is slightly different now. In the viewport settings I used scene lighting not ambient occlusion and I turned on edge lines for surfaces etc... thats all. That's all.

I probably should do an update on this....;)

Which portion gets an error..? What does the error say?

Could I send you an email with photos of what I haven't managed to understand, as well as some other questions about my project? Briefly about my project, I have tried to analyze an area of the city of Vienna using your tutorials and then introduce my shading construction as a solution for uncomfortable temperatures to test its effectiveness. Of course, if you have the time and would be willing to help with a few tips.

well its all explained in the video.

@@PhilippGalvanDesign skimmed through because rushing for an assignment i missed out on that key info

@@visualrhythm9101 Understand. : 😄 good luck with the assignment.

Have you provided a weather data URL? If you did then you can check the following. LB automatically downloads the file and stores it in a folder. Find the folder on your C: Drive Probably under you user account and Ladybug... You should see several files including a stat file. Note: not every epw file has a stat file. If it's not there then you need to find another source.
