Energy simulation error and breps ignored

Hello guys,

While running a simple energy simulation following the tutorials from Youtube so

far I have found 2 issues:

1. 1. The simulation has not run correctly because of this severe error:

** Severe ** Problem in interior solar distribution calculation (CHKBKS)

That happened after running the energy simulation. I will attach the file and image I´m working with since maybe the geometry could be the problem. (Attached image)

2. Trying to visualize EP results in colored surfaces and one of my BREPS is ignored

(Attached image)

Mox,

The EnergyPlus error is because your geometries are slightly nonplanar. I would make them planar as the slight curve doesn't make a major difference in the results but adds to the analysis time and creates errors such as the one above.

For the second issue set recallHBHive_ to True and see if it reloads the results.

Mostapha,

Thanks for the response, I did as you suggested, made every surface planar and recalled de HBHive and still it does not seem to work, apparently all the curved that form the geometry are taken into account but the surfaces are not.

What could be the problem?

Mostapha,

While the curved geometry certainly makes the simulation unnecessarily long and is to blame for the CHKBKS in this case, Luis's issue here as to why the surfaces were not being colored was of a different nature. From what I have found, it was actually related to zone names. Luis had connected the same input for zoneName and zoneProgram in order to avoid duplicate names:

This should normally be fine. However, the insertion of the ":" in the zone name completely messes up my script for parsing the zone names, which parses it out of the eio using the ":" as a separator. Accordingly, I added a .replace() for this character whenever it is included in a zone name. While I was at it, I also put in a bit of code that senses the number of other zones on the canvas to avoid the duplicate name issue that prompted this issue in the first place (it's an issue that has been bugging me for a while):

Luis, you can find your working GH file attached. The CHKBKS issue is discussed on many other discussions so I will not cover it further here:
