Meshing of Hood Challenge

Aim:

To mesh the hood geometry of a car with the given quality criteria.

Objective:

Target Element Length = 5 Units

S.No.	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
11	Tria %	10

Procedure:

Initially we will be importing the geometry model into hyper mesh as shown in the image below.

Since our model will be having solid we will be deleting the same and keep the surfaces alone.

The components which are available for the hood model are shown in the images below.

Now, we will be extracting the mid-surface for these components separately and then assign separate collector ID’s for the mid-surfaces also which are shown in the images below.

Since the geometries are symmetric, we will be masking half of the surfaces in all the mid-surface components and then it will be reflected which will help us in reducing the time for meshing the whole component. Before we will be setting the quality criteria by either clicking on elemcleanup options or then selecting the edit criteria option to input our values for the quality criteria which will also help us to show the failing elements visually in a colour representation.

The final meshed components which quality all the given quality criteria, having proper mesh flow and feature capturing are shown in the images below.

Conclusion:

This is the final meshed image with all the components satisfying the quality criteria.
