Week - 5 - 2D meshing for Plastic components

Objective

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 the given element Quality criteria.

Target Element Length = 1 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	3
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	0.5
6	Max. Length	3
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	30
10	Max angle Tria	120
11	Tria %	15
12	Jacobian	0.7

CAD Model

Procedure

1. Topo

2. Orient

3. Geometry Cleanup

4. Measure Thickness

Measure All Thichness

5. Mid Surface

Different Type Of Tool Use Mid Surface Generation.

• Offset
• Middle Single
• Middle Multi
• Middle In Curve

6. Quality Set

7. Mesh generation

Use Best Mesh tool for Mesh Generation and then improve mesh with quality and mesh pattern.
