Week 6-Meshing of Hood Challenge

Follow the below-mentioned quality criteria, mesh the component given below and assign thickness:

Target Element Length = 5 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	8 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

Procedure:

GEOMETRY

1. Import the geometry into the hypermesh environnment.

2. Extract the midsurface with midsurface command.
3. Perform a geometry cleanup. Provide the quality criteria as given in the objective.
4. MESHING 4.Press F12 to open the mesh tab.
   5. Since Meshing was irregular at some places, it was easier to mesh the mid-surface by first dividing them into smaller pieces and work on them individually. Then Organize it back together with the organize tool from tools tab.
   7. 
   8. QUALITY CHECKS
   9. 
      7. Next part is to check the quality criteria and solve the errors wherever quality failed.
      8. This can be done in the Qualityindex tab. The Element Optimize tool and place nodes can be very helpful to remove errors significantly.
      9. .
      10. 
      11. Make sure to remove rotating quads by rebuilding mesh wherever required. Splitting the trias using split or combine and optimize command can also remove the trias.
      12. To assign thickness to the model, we create a property and a material and then assign thickness.

Conclusion:

Geometry cleanup, mesh generation, and check for quality were done for the given model.
