Week 6-Meshing of Hood Challenge
2D MESHING OF HOOD
AIM:To mesh the given HOOD component and to assign thickness.
TO VERIFY:
To check the quality index of each and every component in given Hood.
GIVEN HOOD COMPONENT:
INNER EXTRACT:
OUTER EXTRACT:
HINGE REINFORCEMENT EXTRACT:
LATCH REINFORCEMENT EXTRACT:
PROCEDURE:
STEP 1:To start the procedure first step to import the model in import geometry option as .STEP file.
STEP 2:For 2D mesh we have to extract midsurface of the component,before start extracting midsurface first step is to delete the solid part in the component using this option given below:
For extracting Midsurface go to geometry_Midsurface in panel area.
Offset+planes+sweep has been used as a extraction option to extract Midsurface.
- After extracting Midsurface we have to split the washer line wherever they needed for better mesh
- For an example I have made a Washer split in the Hinge component :
To use washer split go to Quick edit in Geometry and select washer split option I have used offset value as 5
After created Washer split:
To mesh the component go to 2D mesh option then select Automesh Below:
Element Size for mesh is 5 and mess type is mixed.
Each and every component is meshed individually.
INNER EXTRACT 2D MESH OUTPUT:
OUTER EXTRACT 2D MESH OUTPUT:
HINGE REINFORCEMENT EXTRACT 2D MESH OUTPUT:
LATCH REINFORCEMENT EXTRACT 2D MESH OUTPUT:
NOTE: After meshing next step to check whether the mesh is proper if not we can increase the node or decrease the node to make the mesh align proper.
Then the next step is to check the quality index with the given quality criteria.
| S.N | Quality Criteria | Value |
| 1 | Aspect Ratio | 5 |
| 2 | Skewness | 45 |
| 3 | Warping | 15 |
| 4 | Taper | 0.5 |
| 5 | Min. Length | 2mm |
| 6 | Max. Length | 8mm |
| 7 | Min angle Quad | 45 |
| 8 | Max angle Quad | 135 |
| 9 | Min angle Tria | 20 |
| 10 | Max angle Tria | 120 |
| 11 | Tria % | 10 |
worse case of Quality index each and every component are:
INNER EXTRACT FAILURE OUTPUT:
OUTER EXTRACT FAILURE OUTPUT:
HINGE REINFORCEMENT EXTRACT FAILURE OUTPUT:
LATCH REINFORCEMENT EXTRACT FAILURE OUTPUT:
To clear these failure we have to use the cleanup tools shown below:
NOTE: element optimize and smooth option are the best one to clean the error.
CONCLUSION:
After checking the quality index the final output is:
