Hello,
I'm busy with a shell model with the rough size of 1200x150x260mm. When the mesh is getting smaller around a bolt
fixture, the displacement/strain and stress is going up. When i modelled a radius of 10 in this area, i'm having the same problem (see picture).
| mesh | Stress [Mpa] | Displacement [mm] | Strain (e-4) | Largest welds [mm] |
| 40 | 34.88 | 0.1935 | 3.052 | 13.1 |
| 35 | 32.37 | 0.18 | 2.783 | 11 |
| 30 | 35.78 | 0.1624 | 3.684 | 12.6 |
| 25 | 29.46 | 0.1241 | 3.055 | 9.7 |
| 20 | 30.26 | 0.1067 | 3.297 | 9.6 |
| 15 | 27.61 | 0.1061 | 3.19 | 9.6 |
| 10 | 30.2 | 0.1085 | 3.419 | 11.2 |
| 5 | 34.77 | 0.109 | 4.191 | 12.6 |
| 5 & 3mm refinement @ peakstress | 43.07 | 0.109 | 4.773 | 12.9 |
| 5 & 2mm refinement @ peakstress | 115 | 0.4296 | 12.37 | 19 |
Is it safe for me to say that the 20mm mesh gives the most accurate solution ?
At that moment i thought the displacement and strain where converged (even the stress).
Is there a basic rule for a limit on the refinements on shell models in solidworks ?
Thanks
in advance,
