Week 6- Challenge

OBJECTIVE:

The objective of this challenge is to mesh the bonnet hood part of the car and assign thickness with the 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
11	Tria %	10

CAD MODEL IMAGE:

1. LATCH

2. HINGE

3. INNER EXTRACT

4. OUTER EXTRACT

PROCEDURE:

Step-1: Importing the Geomentry

File->Import->Geomentry.

Step-2: Save the File.

File->SaveAs->Model.

Step-3: Creating the midsurface

Geomentry->Midsurface->surf->displayed.

create individual midsurface for each component seprately.

Step-4: set up file criteria.

Preferences->File criteria Settings.

set the target element to 5, minimum as 2 and maximum as 8.

Step-5: midsurface cleanup

Geomentry->Autocleanup->Surf->Displayed.

we can cleanup the surface either manually or auto cleanup.

Step-6: Creating Automesh.

2D->Automesh->Surf->Displayed.

set the element size as 5 and element type as Quard.

Step-7: Quality checks

the following Quality checks and Quality criteria are checked

1. Warpage
2. Aspects
3. Skewness
4. Min. & Max. Length
5. Cell Squish
6. Jacobian
7. Equia Skew
8. Area Skew
9. Taper
10. Min. & Max. Tria Angle
11. Min. & Max. Quard Angle
12. Edges
13. Normal
14. Dependency
15. Quality Index

Step-8: Creating Properties for the geomentry

Step-9: Creating Material for the geomentry

step-10: assigning the properties and material to the respective components.

Step-11: Save

RESULT:

The given component is meshed with respect to the given quality criteria. the Quality checks and Quality criteria are checked in the meshed component.
