Project 1

PROJECT1: DASHBOARD

OBJECTIVE

In this project for the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component, the thickness has to be assigned.

Quality criteria

S.No	Quality Criteria	Value
1	Target/Average length	4
2	Minimum Length	2
3	Maximum Length	6
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

• Import the CAD model into ANSA.
• Then go to utilities – checks – geometry check to do geometry check whether any free edges, cracks on the surface of the components.
• Then topo the surface to clear the free edges and unwanted cuts.

• Then give the topo – faces – orient to orient the all surface.

• Measure the thickness of the components.

• Then extract auto mid-surface by topo – faces – mid-surfaces – skin but the auto mid-surface shows error so we go for manual mid-surface using topo – faces – offset.

• For the gog house feature in the CAD model we have to create the curve using mesh – perimeter – feat2curve. To convert the cons to curve.
• Then create new surface using the curves by topo – faces – new.
• To extract midsurface for ribs use topo – faces – middle option.

• Separate the components with different PID and assign the thickness.
• Before meshing the components give perimeter length and macros length, by mesh – perimeter – length.
• Then give the mesh parameters in utilities – mesh parameters.

• Then give quality criteria by clicking F11.

• Then to achieve the quality use mesh – shell elements – reconstruct/smooth.

. CONCLUSION

Finally, the dashboard CAD model is convert into FE model by extracting mid-surface geometry check and with required quality criteria .

LEARNING OUTCOMES

Learnt different typed of midsurface extraction methods and mesh them with zero quality errors in ANSA pre-processors.
