Week 3 - 2D meshing for sheet metal

AIM:
For the given Hood model, Take the mid surface for all the components after checking the geometrical errors and mesh the mid surface with the given element Quality criteria. (Refer the table Below for the Quality criteria).

OBJECTIVES:

Take the mid surface for all the components after checking the geometrical errors and mesh the mid surface with the given element Quality criteria.

WORK FLOW:

Step 1: Check the geometrical errors.
Step 2: Check Quality criteria.

S.No	Quality Criteria	Value
1	Target/Average length	5
2	Minimum Length	2
3	Maximum Length	7
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

Step 3: Creating midsurface through skin process.
Step 4: Geometrical error checkup(cons near by near cons and hot points).
Step 5: Check the PID.
Step 6: Check the mesh properties.
Step 7: Check the target lenth and minimum length.
Step 8: Apply the mesh through best mesh, then adit the tria mesh(swap, improve, smooth and split) at boundary.

Conclusion:

In this hood model i get desire mesh and good result. As a begineer in this field it take time to mesh and understanding the prrocess of mesh and functioning of comands.
