AIM- To mesh the given Car's Hood.

TOOL USED-HYPERMESH

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
10	Tria %	10

PROCUDURE-

STEP 1.

Examine the component for any distortion present on it, if any fix it. Check for the symmetry , as this could give us a chance to use reflect command from tool option. In the case of our Hood component it is symmetry so, deleting the half of the symmetric part.

STEP 2.

Now, Deleting the solid, as we need the surface of the component. For deleting, we use the shortcut key, F2 from our keyboard and then select solids, select the whole component and click on delete entity option.

Our components solid parts gone vanished, We have got the whole and pure surface of the component.

STEP 3.

Again, check for any distortion, which was not visualized during first attempt. If any clear it and fix it.

STEP 4.

Now, Take out the mid-surface of the parts of the component, Here we have Latch, Hinge, Outer Panel, Inner Panel. We are taking out the mid-surface part by part for each at a time.

STEP 5.

After the processing of the midsurfacing, we are doing geometry cleanup for each of the parts. we are going into Geom command and using various tools and options to cleanup the midsurface.

The cleanup should be done in such a way that, arouses the questions like, How could be the mesh flow? what are the quality criterias it should be approached? etc.

INNER PANEL-

STEP 6.

Mesh it with the given quality criteria. Make sure to mesh it not at a single shot but part by part to attain the proper feature capturing along with the proper mesh flow. Also make sure that there aren't any trias in the fillet and hemming portion.
