well this is embarrassing.....  turns out I wasn't waiting long enough on my slow PC. Now onto updating Energyplus!

Hi Ben,

How long have you waited for the process to run before you kill it?  Copying LB_KB and HH_HB usually take several seconds now that we have added a lot more classes and functions that take time to copy to the menory.

Hi Chris,

 

It's taking upwards of 4-5 minutes, so I was wondering if something was wrong. Sounds like something might be up then if it's only meant to take several seconds?

 

I'm hopefully getting a PC upgrade in a few days so I'll be able to compare. It should be a fresh install of Rhino/GH/LB+HB so that might fix things up as well.

 

Cheers

Hi Ben,

Is that the case both for Ladybug and Honeybee? Ladybug shouldn't take long at all to load. In case of Honeybee the first time that you let it fly, it downloads a number of files that you can find in installation folder. I wonder if that is the reason of 4-5 minutes?

It is the case for both.  I was thinking it could have been an issue with attempts at downloading. I'm stuck behind a rather strict corporate firewall.

 

I noticed that Openstudio_standards.json was one file that was attempted and blocked, so I got a copy of that downloaded separately. Still no fix. Are there more specific files that are needed?

 

If I can get the firewall relaxed for an initial run should this fix it up for good?

 

Thanks for the help

I'm not sure if firewall is the reason since Ladybug doesn't download anything once you let it fly. Is that also the case when you insert other GHPython components into canvas?

Let us know if changing your system didn't solve the issue. There might be something strange going on with copying data to sticky.

Not really related to your issue but in case you don't know, once you let them fly you will be fine for that instance of Rhino and you don't need to do it again.

Hnn. This is an interesting case. If your Rhino, Grasshopper and GHPython are all up to date then you are not missing anything basic. Keep me posted about what happens on your new machine.

Thanks for the help guys, much appreciated.  I think it's my system and will know for sure when my new one arrives. A colleague who hasn't updated HB/LB only take a few seconds.

 

Will keep you updated.

Hi Ben,

Out of curiosity. are you able to drop the normal GHPython component in the Maths tab onto your canvas?  That will give us an idea if it is something specific to LB+HB or something that more generally happens with GHPython on your system.

Hi Chris,

 

I am able to drop it on without any issues. Of course it has a warning that I have no script to execute!

 

One thing that Honeybee says after it has run is that Schedule = OA already is existed in the library, please rename on of the OA. What does this mean?

 

Hopefully my new system will be around this week to test.

Hi Ben,

Sorry for taking so long to get back.  I can tell you what the error means: the component is saying that the schedule for Outdoor Air (OA) is already in your openStudio library.  So my guess something is going wrong in the download of the OpenStudio libraries that automatically happens when you drag and drop the HB component onto the canvas the first time.

What is your internet connection like on your machine?  Is is stable? Is there a firewall or anything that could block your access to the site app.box?

There is a workaround for this if this is so.  You will have to download the openstudio libraries here:

https://app.box.com/s/y2sx16k98g1lfd3r47zi

and then copy and paste them into a folder that you create in this location of your computer:

C:\ladybug\openstudio

If there is a folder there already, then delete it.

My guess is that something similar might be happening for Ladybug and the Radiance functions that it downloads and uses.  I can give you more instructions if this first workaround helps.

Hi Chris, no worries.

My internet connection is behind a corporate firewall and very difficult to get around, so I agree it could be an issue here.

 

Unfortunately the openstudio files downloaded and placed in the spec'd location didn't have an effect.

 

It did however highlight for me that not all content is defaulting to c:\ladybug.  Model results seem to go between that location and the appdata\roaming folder for ladybug instead.  I copied the openstudio files into there as well, but no luck.

 

Now, which is even stranger, my GH file asks for HB and LB to be flown even after the file has initialised (346.7 seconds...), so I have to delete and re-drop them onto the canvas.

 

All very strange, and my colleague who is running an older version of HB and LB doesn't have these issues.

 

Last but not least, these issues are happening on my new system as well.

 

Thanks for all the help, let me know anything you ned from me to help identify what this could be!

 

Cheers
