PROCEDURE:-
IMPORT THE MODEL and CHECKING FOR GEOMETRY:
1. Import the given Hood Model in ANSA, File >Open.

2) Cons resolution giveing con res as 1
3) topo to check connectivity
4) orientation
5) Geo check and error cleanup

6) midsurf creation using middle (multi) for features like teeth and fins , offset for region with constant thickness we can create midsurf

7) giving quality criteria

6) Meshing , now using suitable meshing method(best, spot map )
we can mesh the mid surf


7) after meshing we need to fix elelments having quality issues we can do this by using reconstruct, smooth ,fix quality option as required
8) due to some triple con some of the elements may fail we should keep the no. as low as possible.


Result- midsurf created and meshed
no. of elements=8762
off elelments=67
