Week 6-Meshing of Hood Challenge

To extract the mid surface for each component and mesh the given

hood component with the given target size of 5 mm mentioned quality

criteria.

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 :-

1) Import the model.

2) Extract the midsurface for the each component.

3) Cleanup the component.

4) Mesh.

5) Reflect the mesh.

6) Check quality index.

Import the model in step file.

Go to preference and give all mentioned dimensions then apply on

the component with on the hinge part only remaining all in switch

of mode.

Extract the mid surface of the hinge.

And also cleanup the mid surface of hinge.

After that doing mesh of the mid surface of the hinge.

Then using quality and find the errors with using tools and doing

quality mesh of the hinge.

After that find the edges with using edges tool.

Then combine the elements and clear the edges problem.

Then reflect the hinge go to option select element click on

displayed and duplicated the current component select the

nodes and base point then hinge reflection done.

After that assign the thickness of property id.

After the hinge reflection switch of the hinge and switch on

the latch remaining all switch of the component.

Then midsurfacing of the latch and autocleanup the latch.

After that meshing the latch and clear the drag elements. incase formed

any duplicate element then will remove duplicate elements and create

the new elements on that place.

fig. mesh of latch

After that the proper mesh you would get quality mesh and find the

edges and clear the all duplicated and clear the errors.

After that assign the property id.

After that finish the latch and switch of the latch and switch on the

outer component toggle the lines and create new line conviently for doing

meshing.

fig. Outer midsurface

After that doing mid surface of the outer hood and divide into two

equal parts and cut the one part of outer wood and will create a

middle line on anglar hood and then doing mesh of the outer wood.

Then finish the proper mesh and remove unwanted nodes and elements

than will get a quality mesh after completion of meshing reflect the

outer hood component same as hinge.

After that go to tool and select elements than displayed and click on

duplicate select the nodes and base points then reflect the outer

hood.

fig. Outer panel

after finish the outer panel and will go to inner hood.

fig. inner panel

Toggle the lines in this component switch off the hinges and mid surface

of the outer panel and doing mesh of inner panel.

After that inner panel mid surface divided into two equal parts and deleted

the one part of inner panel and then doing mesh and remove unwanted nodes

before meshing because the small nodes created big problem doing mesh.

Then delete the duplicate components carefully and create new elements.

After finish the meshing mesh reflect the inner panel and click on the duplicate

then reflect the inner panel.

RESULT :-

The given hood assembly is successfullly meshed according to the mesh quality

provided and quality checked.

CONCLUSION:-

In this challenge we learnt how to mesh of the hood component and

how to mid surface also we learnt mask, quality index and organize

and reflect, find edges tools.
