Week - 4 - 2D meshing for Plastic components

Aim: For the given Plastic Bottle Cap model, check for the geometrical errors and take the mid surface by suitable mid surfacing techniques. PID and Thickness assignment has to be done for all the mid surfaces. Mesh the same with given element Quality criteria.

S.No

Quality Criteria

Value

1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	3
4	Aspect	3
5	Warpage	15
6	Skewness	45
7	Jacobian	0.7
8	Minimum Quad Angle	45
9	Maximum Quad Angle	135
10	Minimum Tria Angle	30
11	Maximum Tria Angle	120
10	Tria Percentage	15

Working Procedure:

Step 1:Check the geometrical errors. Use auto fix and it gives zero errors.

Step 2: Check the quality criteria.

Step 4: Check the mesh parameters.

Step 5: Check the length parameters.

Step 6: Create the mid surface for the all faces.

Here for threads and teeths Create middle curve and project on the surface, then use New command it will creates the mid surface.

Issue: I have getting problem while projecting the cons to on other surface, the projecting surface is disappearing, and also two surfaces intersecting.

Learning out comes: Creating mid surface at complicated area like threds and variable thickness.

Conclusion: Due to above mention issue i have not get mesh.
