MESHING A HOOD OF A CAR USING HYPERMESH
objective:
the main objective is to mesh the given component according to the quality criteria given in the question.
Element quality criteria :
| S.N | Quality Criteria | Value |
| 1 | Target Element Length | 5 |
| 2 | Aspect Ratio | 3 |
| 3 | Skewness | 45 |
| 4 | Warping | 30 |
| 5 | Taper | 0.5 |
| 6 | Min. Length | 3mm |
| 7 | Max. Length | 7mm |
| 8 | Min angle Quad | 45 |
| 9 | Max angle Quad | 135 |
| 10 | Min angle Tria | 30 |
| 11 | Max angle Tria | 110 |
| 12 | Tria % | 15 |
procedure:
- imported the file.
- deleted the solid materials.
- extracted the mid surface.
- performed auto cleanup.
- edited the surface using the options like toggle edges, split surface using nodes and lines.
- added and removed some points using the quick edit option.
- meshed the split surfaces one by one.
- changed the mesh density for the even mesh flow.
- changed the mesh style according to the split surfaces.
- used some options like node edit, edge edit, and edit elements.
- performed the quality of meshing using the option quality index and check elements.
- checked the quality until it satisfies the given criteria.
- checked for any free edges presence.
- used the reflect option to reflect the mesh elements to the body 2.
- saved the file
result:
hence, the given component is meshed according to the given quality criteria.
