Severe errors during Energy Simulation in Honeybee

Hi everyone, my first time here, I started using honeybee recently for my master’s degree, and during an energy simulation some severe errors popped up, was wondering if anyone could help me with this
? I watched the tutorial for Honeybee that Chris Mackey did, and followed suit to it, but unfortunately, I seriously don’t know what happened.
The data shown in the output of the simulation was this one bellow:
{0;0;0}
0. Current document units is in Meters

  1. Conversion to Meters will be applied = 1.000
  2. Current document units is in Meters
  3. Conversion to Meters will be applied = 1.000
  4. [1 of 8] Writing simulation parameters…
  5. [2 of 8] No context surfaces…
  6. [3 of 8] Writing geometry…
  7. [4 of 8] Writing Electric Load Center - Generator specifications …
  8. [5 of 8] Writing materials and constructions…
  9. [6 of 8] Writing schedules…
  10. [7 of 8] Writing loads and ideal air system…
  11. [8 of 8] Writing outputs…

  12. … idf file is successfully written to : c:\ladybug\unnamed\EnergyPlus\unnamed.idf
  13. Analysis is running!..

Done! Read below for errors and warnings:

  1. Program Version,EnergyPlus, Version 9.3.0-baff08990c, YMD=2020.06.23 16:26,
  2. ** Severe ** [ShadowCalculation][ShadowCalculation 1][shading_calculation_method] - “AverageOverDaysInFrequency” - Failed to match against any enum values.

Since I’m a new user, I can’t upload my GH file, if anyone wants to take a look I can upload on Google Drive.
Warm regards

  1. The simulation has not run correctly because of this severe error:
    ** Severe ** [ShadowCalculation][ShadowCalculation 1][shading_calculation_method] - “AverageOverDaysInFrequency” - Failed to match against any enum values.
  2. The simulation has not run correctly because of this severe error:
    ** Severe ** [ShadowCalculation][ShadowCalculation 1][shading_calculation_update_frequency_method] - “30” - Failed to match against any enum values.
  3. The simulation has failed because of this fatal error:
    ** Fatal ** Errors occurred on processing input file. Preceding condition(s) cause termination.

Here’s the link for the file I’m using, if anyone could help me with this one I’d very much appreciate it :slight_smile:

It has probably something to do with the version of energyplus you installed.
With energyplus 9.3 the changed the way of shadow calulation.

(As mentioned in the EnergyPlus 9.3.0 update log, gpus can be used to accelerate computation)

Interesting stuff. The GPU calculation documentation is here under the InputOutput reference:
https://bigladdersoftware.com/epx/docs/9-3/input-output-reference/group-simulation-parameters.html#inputs-10-019

It looks like the whole ShadowCalculation object got an overhaul in E+ 9.3, which is likely to break some things in honeybee. It also seems like this GPU method is slower but it gives users a means to run detailed indoor solar distribution without needing to worry about concave zones (something I know a lot of people on this forum will be happy about).

The best I can offer until we upgrade honeybee is to write out an IDF, upgrade it to 9.3 by opening it in the IDFEditor, manually change the ShadowCalculation object, save it, and use the Rerun IDF component to run the model through E+ and import results to Grasshopper.

Once we upgrade honeybee, you’ll be able to do this all in a more streamlined manner like by using a OpenStudio Measure.

Thank you so much! I’ll try it out here and see how it goes

Hello,
i ran into this same issue.
did you find a solution for it?

Hi Mohamed, still did not find a solution for it, still getting the same problem :confused:
