Assignment 1

PART 1

Objective:-

To perform various preprocessing activities to the given component using geometry cleanup, mid-surface, 2D meshing and elemental cleanup, and finally assigning the property and thickness to component as per the quality criteria.

Target element size- 5 mm

Minimum element size – 3.5 mm

Maximum element size – 7mm

Tools used:-

• Model import,
• Quick edit panel(toggle edges, add/remove points, replace points, filler surface)
• Mid-surface,
• 2D auto-mesh using mixed components,
• Project
• Defeature,
• Temp nodes,
• Smooth,
• Mask.

Procedure followed:-

1. Import the original geometry
3. The first and the foremost job after importing the geometry is that to check whether there are any discrepancies in the model. Cleanup the geometry if required.
4. Now extract the mid-surface of the obtained component.
6. Again geometry cleanup is required for proper mesh, also the holes with less than and equal to 5 mm are to be neglected/filled using filler surface command.
8. Post cleanup mesh the part individually for obtaining the proper mesh.
10. Check for quality criteria for elements so that the element size is not more than 7 mm and not less than 3.5 mm as per required criteria.
11. Assign property and thickness to the component as per the original component. In our model the thickness to be assigned is 0.91 mm.

Conclusion:-

The final meshed surface obtained is attached below.

PART 2

Objective:-

To perform various preprocessing activities to the given component using geometry cleanup, mid-surface, 2D meshing and elemental cleanup, and finally assigning the property and thickness to component as per the quality criteria.

Target element size- 5 mm

Minimum element size – 3.5 mm

Maximum element size – 7mm

Tools used:-

• Model import,
• Quick edit panel(toggle edges, add/remove points, replace points, filler surface)
• Mid-surface,
• 2D auto-mesh using mixed components,
• Project
• Defeature,
• Temp nodes,
• Smooth,
• Mask.

Procedure followed:-

1. Import the original geometry, and perform geometry cleanup. Extract the mid-surface of the obtained component.
3. Again geometry cleanup is required for proper mesh, also the holes with less than and equal to 5 mm are to be neglected/filled using filler surface command.
5. The circle left because the diameter is 20 mm.
7. Perform geometry cleanup again like replace points, toggling edges if required to obtain a cleaner mesh.
10. 2D Meshing each part of the component individually so that a fine mesh can be performed.
12. Final meshed component without any quality criteria deviation or a cleaner mesh which have a fine quality criteria.
14. Assign property and also thickness to the component. In our model the thickness is assigned as 2 mm.

Conclusion:-

The final mesh obtained is as below satisfying all the quality criteria.

PART 3

Objective:-

To perform various preprocessing activities to the given component using geometry cleanup, mid-surface, 2D meshing and elemental cleanup, and finally assigning the property and thickness to component as per the quality criteria.

Target element size- 5 mm

Minimum element size – 3.5 mm

Maximum element size – 7mm

Tools used:-

• Model import,
• Quick edit panel(toggle edges, add/remove points, replace points, filler surface)
• Mid-surface,
• 2D auto-mesh using mixed components,
• Project
• Defeature,
• Temp nodes,
• Smooth,
• Mask.

Procedure followed:-

1. Import the original geometry
3. Cleanup the geometry if required.
5. Mid-surfacing is the next step after cleaning up the geometry.
7. Cleaning up the geometry again for better mesh of the final component.
9. Mesh part individually. Post meshing assign property and thickness to the model. In our model the thickness of the parent component is 1.8 so assigning the thickness as 1.8.

Conclusion:-

The final component with mesh obtained is attached below, satisfying all the quality criteria.
