Week 12:Project 2-Meshing of Rear Wheel Holder challenge

AIM:

For this week's challenge,

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. Download the model from the project assignment.
2. Check the format of the model given. And import the model by selecting the proper format.
3. 
4. Check the model if any other component present in that. If any present of other component in the given separate it by using the organize tool.
5. But I have found some surface as duplicate in the parent body. So I have deleted after moving it to the main component.
6. 
7. For that go to GEOM > MID SURFACE > EXTRACTION OPTIONS > SKIN OFFSET > AUTO EXTRACTION > SELECT THE SURFACE > EXTRACT.
8. 
9. Check the mid with parent component if it’s given good, we can continue.
10. Complete the model by taking the mid surface by using manual or auto mid tools.
11. 
12. Before meshing it always preferred to give the quality criteria. To give quality criteria to MANU BAR > PREFERENCE > CRITERIA FILE SETTING > CHANGE THE VALUES OF QUALITY PARAMETERS ACCORDING TO THE REQUIRED > APPLY > OK.
13. 
14. 
15. Now go to 2D > AUTO MESH > SELECT THE SURFACE > ELEMENT SIZE =5 > TYPE = MIXED > MESH.
16. 
17. Now change element colour mode to by element quality. Here we can see how many numbers of elements are failing due to parameters.
18. I have observed the many elements are failing due to quality.
19. 
20. We have best option to correct most of the element quality with help of mesh rebuild.
21. For that go to 2D > REBUILD MESH > SELECT THE ELEMENTS > REBUILD.
22. 
23. Go to 2D > QUALITYINDEX > CLEANUP TOOLS > use the tools like PLACE NODE, ELEMENT OPTIMIZE, DRAG TRIA ELEMENT and SWAP EDGE.
24. 
25. Before using this option, we should mesh on surfaces.
26. It’s time to assign the thickness property to mesh. We can directly go for auto mesh thickness assign.
27. MANU BAR > MESH > ASSIGN > MID MESH THICKNESS > SOLID MESH = COMPONENT > MID MESH > THICKNESS > THICKNESS OUTPUT > PROPERTY ON COMPONENTS > CALCULATE THICKNESS.
28. 
29. 
30. We could see that it has not given property thickness properly so, we have to change the thickness of elements.
31. For that go to TOOLS > ORGANIZE > COLLECTORS > SELECT THE ELEMENTS (which we want to change) > SELECT THE COMPONENT (which has the proper thickness) > MOVE.
32. 
33. After completing the model, we can go for checking the free edges.
34. For that go to main menu tool > tools >edges > select the component > find edges.
35. 
36. Save the file.
37. 

LEARNING OUTCOMES.

1. making the proper mesh flow.
2. solve the element quality errors.
3. Assign of auto thickness and correcting the thickness.
4. taking the mid surface for complex shapes.
