Follow the below-mentioned quality criteria, mesh the component given below and assign thickness:

Target Element Length = 5 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Warping	0.5
5	Min. Length	2 Units
6	Max. Length	8 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

AIM :- Mesh the given cad model with approprite given values of quality criteria.

PROCEDURE:-

Importe the cad model if it is in step file format or gsp file format.
Extract the midsurface from cad model by using commmand of (geo+midsurface).
After extract midsurface tougle the unnessesary shear lines to reduce working time and unessesary mesh elements.
mesh the cad model with approprite given quality criteria values.
by using command (2D+quality index) we rectify, which elements are exceeding approprite given values of warping,skewness,aspect ratio,ect.
the command (2D+chek element) is used to showing how many number of elements are in warping,skewness,aspect ratio.
if their is more number of failure of elements then use command ( 2D+quallity index) to minimaze the number of failures.
repeat the process untile getting the good results.

CONCLUSION:- we learn how to rectify the Skewness,Warping,Min. Length,Max angle Tria and Min angle Tria ect and how to do proper mesh the cad model. The CAD model after mesh and befor mesh with quality criteria values shown below.
