Very inaccurate Energy Model, Gaps and Irregularities

[Anonymous]

Hello! I'm creating an energy model of my building in order to do some energy analysis on an external engine simulator. Even if I set the settings to the minimum (Analytical Space Resolution = 0.1524 and Analytical Surface Resolution = 0.0762) the model keeps showing large gaps in the roof especially in correspondence with internal wall and in correspondence with variations in shape.

Is the Energy Model still accurate? 
Is there a solution to improve the model?

Thanks!

How exactly did you create this image? 

Did you make use of the AnalyzeEnclosedSpaceVolumes property? If true, the analyzer will also look for bounding building elements and connected analytical grid cells for enclosed space volumes inside the building.

I believe many other properties may also affect the model calculation.

Have you looked at the gbXML output? Maybe that has less gaps?
