Hello, I am trying to run an energy simulation on my structure, which later can be used to generate comfort analysis. But the following warning shows up:

- The simulation has not run correctly because of this severe error: Severe ** GetSurfaceData: There are 3 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.
- The simulation has not run correctly because of this severe error:

** Severe ** For zone: ZONE_0 it is not possible to calculate the volume from the surrounding surfaces so either provide the volume value or define all the surfaces to fully enclose the zone. - The simulation has not run correctly because of this severe error:

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

My original model has curved surfaces, since HB does not accept curved geometry, I had to construct, based on my original geometry, a closed Brep with multiple planar surfaces to run the HB analysis.

It’s possible that the warning from HB is due to the new Brep I created based on my original curved geometry, but I couldn’t find out the root of the problem.

I attached the grasshopper filedec202.gh (645.3 KB)

, in case anyone is willing to help me solve this problem, any help wil be greatly appreciated !!

the script labeled red is where my problem is.

p.s: you can replace the weather file to any other ones
