EnVi Zone Definition - fatal error in EnergyPlus error file

[Michael Lester]

I have attempted to follow the tutorial 7 video for EnVi Zone Definition, using vsuite 0.6 in Blender 2.82.

• Object Properties for EN-COLLECTION is set to EnVi Surface. (location differs to 0.4 in older version of blender, but this seems correct)
• Materials created and assigned to a model similar to the tutorial video
  • Roof, Walls, Floor, Windows, Door
    
• EnVi Material nodes created for each, single node for each using relevant preset e.g. Type = Window (different process to 0.4 but looks legit)
• Vi-Suite nodes as follows, connected appropriately:
  
  • VI Location (source EPW Birmingham or my local custom data)
  • EnVi Geometry (and exported)
  • EnVi Export (zone thermal: temp and humidity checked, and exported)
  • EnVi Simulation
  • 
    

When I click calculate on EnVi Simulation node I get an immediate error as follows:

"Fatal error reported in the EnergyPlus error file. Check the file in Blender's text editor"

I assume means the results1out.err file in the created subfolder but it is empty.

in1.epw matches the selected input epw file

in1.idf looks fine describing the geometry

results1out.dbg/eio/err/eso/mtr are all empty files, as is sqlite.err

Any advice on getting it to work? Or finding the reported error file?

I have also checked in install directory, subdirectories, use appdata locations, and working file locations. No such error file exists.

Sounds alright. Does the vi-suite-log file in Blender's text editor say anything useful? If the results1out.err is empty it means something went wrong before EnergyPlus initiated. If you can post the blend file here I'll have a look.

Missing module called 'codecs':

2021-01-20 17:36:14: Energyplus error: Fatal Python error: initfsencoding: unable to load the file system codec

Traceback (most recent call last):

  File "C:\\Users\\Mike\\AppData\\Roaming\\Blender Foundation\\Blender\\2.82\\scripts\\addons\\vi-suite06-master\\EPFiles\\win32\python_standard_lib\encodings\__init__.py", line 31, in <module>

ModuleNotFoundError: No module named 'codecs'

[Ryan Southall]

Thanks for the report. Looks like I, err hem, forgot to put some EP Python files up on git for Windows.  For now you can try copying over the codecs.py and other files from the linux or darwin directories. Or you can download EnergyPlus 9.3 for windows and copy over the missing files from there. I'll upload them to git when I do the next commit from windows.

[Ryan Southall]

Also, bear in mind only Blender 2.83 is supported.

Missing files should now be in the git repository.

[Michael Lester]

Thanks. Grabbing now, and getting 2.83 LTS from Steam.  I'm using 2.9 for most of my Blender stuff, just still had 2.82 on my system.
Will have a play around next week and report back.

The error log now populates. Immediate fatal error on attempting to calculate the simulation.
in1.idf file attached.

I don't see the idf attachment. Looks like the zone is not being exported but the surfaces are. 

[Michael Lester]

Attachment just keep erroring. Trying again as .txt

[Ryan Southall]

The file confirms that the EnergyPlus zone is not being exported, but the surfaces are. Can you post the blend file here?

[Michael Lester]

Attached. Rename from txt to blend because reasons

[Ryan Southall]

I can't open it. Seems it's gotten corrupted. Try putting the blend file in a zip file. If if won't upload to here, zip files can be uploaded to the github issues page.

[Ryan Southall]

You've got a 100mm thickness of glass in your windows.

[Michael Lester]

Then it is because the script does that. Because the model doesn't, and there is no visible setting to define thicknesses.

[Michael Lester]

Ah. It defaults to 100mm for all measurements in all materials in Envi Material . Even for presets, despite field labels saying, for example, 3mm, 14mm airgap, 3mm.
