Proposition of the best near-optimal combinations in mesh density n along the circumference and integration method for a given admissible global accuracy. The time factor is calculated with the lowest quality proposed solution: 8-nodes C3D8.
| Admissible global accuracy | Best density n and element type | Time factor |
|---|---|---|
| 83.7% | 8-nodes C3D8 | 1 |
| 94.0% | 8-nodes C3D20R | 2 |
| 97.4% | 8-nodes C3D20 | 5 |
| 99.6% | 12-nodes C3D20 | 11 |
| 99.8% | 16-nodes C3D20 | 24 |
| 99.9% | 24-nodes C3D20 | 84 |
| 99.97% | 36-nodes C3D20 | 485 |
| 99.995% | 50-nodes C3D20 | 2 220 |
