Meshing of Hood with the given quality criteria by 2D Meshing
OBJECTIVE:
The objective of this challenge is to mesh the given component (HOOD) has per the given quality criteria and maintain the mesh flow.
The quality criteria to be maintained are Targeted mesh element-5mm

PROCEDURE:
Initially the given component has been imported in the workspace and component has been observed completely.
FIG 1a inner mid surf is exctracted
Geometry clean up is done by toggling the unwanted lines to maintain the mesh flow.
After the geometry clean up the mid-surf has been extracted for all the 4 components.
Then the meshing has been started from complex component namely inner component.
As the inner is symmetric the one part of the inner has been masked and meshing is started.
The mesh is done with the given quality criteria and the given element size is 5mm.
FIG 1b After inner is meshed
Once the mesh is completed the mesh is reflected to another side of the inner component.
After the inner surface the outer surf and other components hinge and latch is also meshed with the given quality criteria.
FIG 2a mid surface of outer hood
In this challenge we can come to know many new tools and shortcuts to get a proper mesh flow,
F6 is used to create, combine, split the elements in the mesh it is used even to reduce tria element in the mesh.
By shift+F3 we can find the free edges in b/w the elements and we can equivance it.
And F3 can replace the nodes so that min elements can be cleared.
F4 can be used to calculate the distance between the two, three nodes and points.
F5 can mask the elements (or) surface.
F12 is used for mesh.
FIG 2b outer hood meshed
The tria element in some regions are removed by using quality index in the 2D option.
Challenges faced :
After the completion of mesh the free is checked, and there are many free edges between the elements and it has been cleared using equivalence and by replacing nodes.
CONCLUSION:
Finally the mesh is done for the given component (HOOD) has per the given quality criteria and the mesh flow is maintained.
