7.3. Tested sizes and results

For method \(G-\mathit{thêta}\) (command CALC_G), the following crowns of the theta field are chosen:

	Crown 1	Crown 2	Crown 3	Crown 3	Crown 4	Crown 5	Crown 6
Rinf	0.1	0.2	0.2	0.3	0.3	0.1	0.2
Rsup	0.2	0.3	0.3	0.3	0.4	0.4	0.4

Identification	Reference type	Reference value	Precision

7.4. Comments

In 3D, there is a slight deterioration in the precision for the calculation of factors compared to equivalent 2D modeling (modeling A).
