We expect simply to calculate
ratio = surface / volume
However, the elements have different dimension, there is size-effect. So that I temporary revise the calculation as
ratio = root(area) / third root(volume)
Please try your own model, and test if still there is size-effet. We still need to consider which surface(of building) we count for “roughness” evaluation. How we handle about windows?
面積 / 体積の比率を計算します. 大きさの影響問題をとりあえず
面積の平方根 / 体積の平方根
としました. 入力のBrepへの割り当てをいろいろと変えて試してみてさい. また計算対象の面をどう考えるか、開口の扱い、など検討してください.
