Week 4
OBJECTIVE
The bottle Cap component is given with various thicknesses in threads, teeth, and ribs. Taking manual mid surface with different procedures and meshing the component with 1mm target element size and mentioned quality parameters.
Bottele cap:
| S.No | Quality Criteria | Value |
| 1 | Target/Average Length | 1 |
| 2 | Minimum Length | 0.5 |
| 3 | Maximum Length | 3 |
| 4 | Aspect | 3 |
| 5 | Warpage | 15 |
| 6 | Skewness | 45 |
| 7 | Jacobian | 0.7 |
| 8 | Minimum Quad Angle | 45 |
| 9 | Maximum Quad Angle | 135 |
| 10 | Minimum Tria Angle | 30 |
| 11 | Maximum Tria Angle | 120 |
| 12 | Tria Percentage | 15 |
Considering the quality parameters, ensuring the element meets the quality criteria for fine mesh flow.
Procedure:
- Bottle Cap model is given for the mid surfacing and meshing the component.
- The geometry was cleaned and checked.
- midsurface is extracted for given geometry.
- And PID assinged for each surface.
- mesh size of 1mm generated for model.
CONCLUSION
The bottle cap component has a varying thickness in threads, a different type of ribs, small hatch and varying faces the mid surface for this component done with a different option, taking it manually and mesh for this component with small elements size but they are fixed with reconstructing and smooth option and achieved with quality option.
