Week - 4 - 2D meshing for Plastic components

Aim:

To check for the geometrical errors and take the mid surface by suitable mid surfacing techniques for the given Plastic Bottle Cap model and Mesh the same with given element Quality criteria.

Procedure:

1. Import the cad model in Ansa.

2. Making the topology for the given model and check for the geometry error.

3. Fix the geometry errors and make the model as geometry clean up.

4. Measure the thickness of the surface area which want extract for the mid surface.

5. Here we using the one of the mid surface extracting technique is offset.

6. By using the Face>middle>multi extract the mid surface for the elements.

7. After the extraction of mid surface there is gap between the coons it can fill up by using the new face create.

8. The mid surface for the elements has been created.

9. Set the average length for meshing.

10. Changing the perimeter and macro length.

11. Setting the given quality criteria.

12. The meshing is done by the best mesh option in mesh generation.

13. By switching the hidden the quality issues were shown and the reconstruction will helps to improve the quality of the mesh.

Learning outcomes:

Learnt to use the various type of tools to create mid surface, to create the surface using middle curve, transform the pattern of the surface in the model and manual mid surface for the elements.

Conclusion:

The given bottle cap model is meshed with given quality criteria using mid surface and assign the various thickness among the surface.

Here the result of the meshing.
