Week 3 - 2D meshing for sheet metal
Methodology:-
1)Import the model
2) Geometry cleanup
3) midsuface extraction
4) perimeter setup
5) quality criteria setup
6) 2d meshing
7) exporting
1)Import the model:-
-The format of the file is .step, then first of all select open - file loaction- choose open model.
-Now selected file will open
2) Geometry cleanup:-
-After import a model, we focuss on geometry.
-it is required for achieve better result of mesh flow.
3) midsuface extraction
- after geometry cleanup , i used offset for hatchs and midsurface feature for hoods wich is easier way to extract mid sufaces
4) perimeter setup
-as per quality criteria the perimeter length is fixed for perimeter and macros
5) quality criteria setup
- below is used quality criteria

6) 2d meshing
- proceeding with 2d meshing
- using mesh - best - select/visible to create mesh
- using split,swap,reconstruct,reshape the off elements were cleared
7) exporting
-exporting the model as per required
i have exported as .ansa
