Project 1-Meshing of Rear Wheel Holder challenge

Aim:Generating midsurface and geometry clean up on the given component and proper mesh flow wuth low tria concentration.

PROCEDURE:

1. Download the model from the project assignment.
2. 
3. Check the format of the model given. And import the model by selecting the proper format.
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. For that go to GEOM > MID SURFACE > EXTRACTION OPTIONS > SKIN OFFSET > AUTO EXTRACTION > SELECT THE SURFACE > EXTRACT.
7. 
8. Check the mid with parent component if it’s given good, we can continue.
9. Complete the model by taking the mid surface by using manual or auto mid tools.
10. 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.
11. 
12. Now go to 2D > AUTO MESH > SELECT THE SURFACE > ELEMENT SIZE =5 > TYPE = MIXED > MESH.
13. Now change element colour mode to by element quality. Here we can see how many numbers of elements are failing due to parameters.
14. I have observed the many elements are failing due to quality.
15. We have best option to correct most of the element quality with help of mesh rebuild.
16. For that go to 2D > REBUILD MESH > SELECT THE ELEMENTS > REBUILD.
17. Go to 2D > QUALITYINDEX > CLEANUP TOOLS > use the tools like PLACE NODE, ELEMENT OPTIMIZE, DRAG TRIA ELEMENT and SWAP EDGE.
18. 
19. we can also use some extend option to join the mesh elements for the ribs.
20. Before using this option, we should mesh on both surfaces.
21. Now go to 2D > MESH EDIT > IMPRINT > SOURCE= NODE LIST > SELECT THE NODES > DESTINATION = ELEMENTS > REMAIN = DESTINATION > CREATE.
22. It’s time to assign the thickness property to mesh. We can directly go for auto mesh thickness assign.
23. MANU BAR > MESH > ASSIGN > MID MESH THICKNESS > SOLID MESH = COMPONENT > MID MESH > THICKNESS > THICKNESS OUTPUT > PROPERTY ON COMPONENTS > CALCULATE THICKNESS.
24. We could see that it has not given property thickness properly so, we have to change the thickness of elements.
25. For that go to TOOLS > ORGANIZE > COLLECTORS > SELECT THE ELEMENTS (which we want to change) > SELECT THE COMPONENT (which has the proper thickness) >
26. After completing the model, we can go for checking the free edges.
27. For that go to main menu tool > tools >edges > select the component > find edges.
28. 
29. Save the file.
30. 

LEARNING OUTCOMES:

1. use of mesh edit option like extendeding the mesh upto the surface.
2. Assign of auto thickness and correcting the thickness.
3. taking the mid surface for complex shapes.
