ANSA Project - DASHBOARD - Midsurface extraction and Shell Meshing

AIM

To check for the geometrical errors for the given Dashboard model 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	Skeweness	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
12	Tria Percentage	15

PROCEDURE

The given Dashboard model is checked for Geometry errors and once the check geometry is done we set the Perimeter, Macro Length as 1 in Mesh mode. Length is set as 1 while taking midsurface.

Geometry check is done.

Before Offseting the surfaces, We have to measure the thckness of the surfaces for taking the midsurfaces.

Thickness were measured in order to take the midsurfaces for those parts.

On basis of the thickness, Seperate properties were created.

Now midsuraface were created using Offset option in FACE under TOPO mode.

For these types of cylindrical portions we have offset the faces at length of 1mm.

And All the offest faces like Cylindrical portions and ribs are extended to the main midsurfaces like,

Mixed mesh were deployed on the surfaces and good mesh flow and passing on quality criteria is also concentrated.

Meshed were delopyed with a good flow.

After meshing is done. Some quality failures are rectified manually by observing each and every portions.

And Finally, Shell as Solid is given and with the assigned thickness the shells were converted to solids.

Make the Parent surface as transparent in property option and check the midsurface with the parent surface.

Thus Midsurface and Meshing is done.

LEARNING OUTCOME

Well learnt on taking midsurfaces on crucial surfaces and deploying mesh on the parts. And learnt on maintaining a good mesh flow.

CONCLUSION

Hereby I concluding that Dashboard model has been taken midsurface and mesh has been deployed.
