Hi everyone,

one of my colleagues wants to post a discussion but they didn’t accepted her here on the GrassHopper forum yet. I post the following for her so that you, brilliant minds, are able to start looking at it…

She will join the conversation as soon as they accept her.

Thanks in advance,

Claudio

Hi guys,

I´m new in this forum and I hope I can find here a solution of my problem.

I´m tring to do an energy simulation (and the next step would be the optimization with octopus) with honeybee and ladybug.

I´m analyzing a floor of 2600mq with more than 2/3 of external walls glazed. I´ve got also 174 fins along the perimeter.

The problem is that when I run the simulation I recive these errors for each window:

** Severe ** GetHTSubSurfaceData: Surface Openings have too much area for base surface=EEE8110BF0A843E9A620_9

** ~~~ ** Opening Surface creating error=GLZ_0_EEE8110BF0A843E9A620_9_A2E7F42406024C9A833A

** Severe ** GetSurfaceData: Zero or negative surface area[0.00000], Surface=EEE8110BF0A843E9A620_9

If i have understood well, according to .err file, the dimension of the window in rhino seems to be bigger then the wall. But it isn´t! i mean i´ve tryed also to put a frame to the windows or to scale them but i got the same results.

Do you know why or how i can solve it??

aaand it isn´t finished! even if i checked my Rhino with “SelCrv, SelBadObject,selLine…” and i got “only” 303 surfaces and 3 polysurfaces i still can´t find the degenerate surface for which i have these errors:

** Warning ** GetSurfaceData: There are 2 coincident/collinear vertices; These have been deleted unless the deletion would bring the number of surface sides < 3.

** ~~~ ** For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;

** Severe ** GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.

** ~~~ ** These surfaces should be deleted.

** ~~~ ** For explicit details on each problem surface, use Output:Diagnostics,DisplayExtraWarnings;

** Fatal ** GetSurfaceData: Errors discovered, program terminates.

…Summary of Errors that led to program termination:

… Reference severe error count=7

… Last severe error=GetSurfaceData: There are 1 degenerate surfaces; Degenerate surfaces are those with number of sides < 3.

Someone can help me? it´s three days that i´ve been struggling with this work, but still can´t find the solution

Here i attach the rhino and gh file

Thanks a lot

Claudia
