Week 6-Meshing of Hood Challenge

Meshing of Hood

AIM

To generate the mesh in the given model with proper element quality and give proper thickness on it.

PROCEDURE

Import the model.

steps Involve

1. Extracting Mid-surface and assigning properties.
2. Meshing the surface with in the given quality criteria.

Quality criteria:

S. No	Quality criteria	Value
1.	Aspect ratio	5
2.	Skewness	45
3.	Warping	15
4.	Taper	0.5
5.	Min. Length	2
6.	Max. Length	8
7.	Min Quad Angle	45
8.	Max Quad Angle	135
9.	Min angle Tria	20
10.	Max angle Tria	120
11.	Tria %	10

After importing the geometry, the geometry is checked for any missing surfaces

5 component can be extract seperately.

And delete the solid and to create the midsurface on it.

midsurface can be extract properly.

Outer_extract_body1

Delete the soild.

And extract the automesh with element quality of 5 units.

Mesh the element.

Inner_extract_body1

Delete the soild.

And extract the automesh with element quality of 5 units.

Mesh the element

Hinge_reinforcement_extract_body1

Delete the soild.

And extract the automesh with element quality of 5 units.

Mesh the element.

Hinge_reinforcement_extract_body2

Delete the soild.

And extract the automesh with element quality of 5 units.

Mesh the element.

Latch_reinforcement_extract_body1

Delete the soild.

And extract the automesh with element quality of 5 units.

Mesh the element.

Target Element Length = 5 Units

Failure can be cleared by the qualityindex, element cleanup, checkelement.

All element can be check with proper quality criteria.

Create the material with proper young's modulus, poison ratio, rho

Create the property with assigning the matrial and thickness to the component.

Use TOOL < NORMAL

CONCLUSION

For the given hood panel mid-surface is extracted and mesh is generated with in the given quality criteria.
