Hi, can I ask if the “ironbug” in the video is already available to download somewhere?


#4

These components are so powerful. I want to know when it will join the Ladybug or how to download them?


#5

@skyly @minggangyin, I am currently testing these components in two of our real projects, and my colleague is also using in another project. I am thinking it will be mostly ready for the public test next month.


#6

@MingboPeng I am following your workflow,but Honeybee export to OpenStudio is different.Could you upload the component which you are using in the video.

The HVACSystem input is missing. I cannot connect the ironbug HVAC to OpenStudio

Your component is June 10 2018
OS-1
My updated latest component is July 01 2018

@MingboPeng I found the June 10 version Honeybee export to Openstudio on GitHub.But when I set True for running,the Rhino 5 crashed.


#8

@minggangyin
which OpenStudio version you are using?
How did you install the plugins?
I haven’t created an automatic installation process, you will need to do following steps manually.

1.
Please download this attachment Ironbug.zip (1.4 MB), and unzip to C:\Ironbug
Copy “OpenStudio.dll”, “openstudio_csharp.dll”, “openstudio_translators_csharp.dll” three files from OpenStudio folder to “C:\Ironbug” folder.
ps: OpenStudio 2.5 is required.


2.
Move “Honeybee_Export To OpenStudio_1.ghuser” to “User Object Folder”

Move “Ironbug.ghlink” to “Components Folder”

3.
Restart the Grasshopper.

@MingboPeng Thank you so much. Yesterday I just download the Ironbug master zip file from GitHub and copy the unzip folder to Grassshooper Compotent fold. Now I remove the relate folder and install Ironbug using your method, It worked fine. Ironbug is an amazing and powerful plugin. I loved it.

And I found some bug for Ironbug. It supports the 1 speed and 2 speed CoilCoolingDX, but does not support CoilCoolingDXMultiSpeed.

I sugget Using merge tree component for air loop modeling.

Dear MingboPeng

Thank you for your tutorial!:star_struck:

Thanks for letting me know.
OpenStudio team hasn’t finished the MultiSpeed DX Coil in their API, and I have added a warning to both heating and cooling MultiSpeed Coil.
