Week 4 - 2D Meshing for Sheet Metal

Aim: For the given CCB CAD model, Check for Geometry cleanup, Take the midsurface, and mesh it with the below 2D element Quality Criteria.

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

Procedure-

1) import the model to ansa

2) using topo in case if there is no connectivity and use con res

3) geo clean up

4) creating mis surf using skin or offset

5)giving quality criteria

6)meshing and assigning thickess
