Hello all,

I am totally new to this program and this forum. I apologize, I do know how to solve these errors listed below. Any help or guidance towards the right direction would be greatly appreciated!

I attempted to edit the IDF file by editing the ShadowCalculation object accordingly:

ShadowCalculation,
  PixelCounting, !- Shading Calculation Method
  Periodic, !- Shading Calculation Update Frequency Method
  20, !- Shading Calculation Update Frequency
  15000, !- Maximum Figures in Shadow Overlap Calculations
  SutherlandHodgman, !- Polygon Clipping Algorithm
  512; !- Pixel Counting Resolution

However, when I save the IDF file and try to import it into OpenStudio, I receive the following error:

"File is not valid to draft strictness. Check that IDF is of correct version and that all fields are valid against Energy+.idd.


The collection is INVALID at strictness level 'Draft', because of the errors:
Field level data error of type DataType .
Error is in an object of type 'ShadowCalculation', named '', in field 0.
Additional information about the error type: field-level data is of an incorrect type.
Field level data error of type NumericBound .
Error is in an object of type 'ShadowCalculation', named '', in field 2.
Additional information about the error type: numeric data violates a min or max bound."

Do you have any suggestions?

Thank you, Cullen

I am having a terrible time trying to address degenerate convex surfaces in my EnergyPlus model.

I was able to isolate and delete some surfaces but Surface 75 (attached) is significant.

I have been told by support that I can use something called ShadowCalculation, the PixelCounting method. However, I cannot find any resources online.

Do you know how to use ShadowCalculation's PixelCounting method? Or do you know of a way that I can prevent degenerate convex surfaces from happening to begin with?

Thank you, Cullen

Thank you so much!

Hello,

I have installed Sketchup 2017 Make, Sketchup Pro 2020 (Trial), OpenStudio 3.0.1, and EnergyPlus 9.3.0. I am using windows 64 bit.

If I remember correctly from my previous success, the next step is to go into the extension manager and import the openstudio ruby extension. However, there is no accessible .rbx file to select in the Ruby folder under the OpenStudio folder. (I have looked elsewhere even though I know this is the right spot)

edit: I see that in my previous successfull OpenStudio 2.9.1 folder there was a folder called "SketchUpPlugin" that is not in the openstudio 3.0 folder.

Do you have any advice?

Thank you, Cullen
