| 4 | Taper | 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 |
Procedure :-
1) We have a given model of wheel holder. First we need to imort this model using import tool.
2) We have to remove surface fillet which is less than given mesh size. for that go to 'defeature' tool in 'geom' panel. Give min and max radius, select displayed surface and find fillets and remove it. Also delete unnecessary surface which create bad mesh.
3) Next we have to go for midsurface creation. for that go to 'Midsurface' tool in 'geom' panel. then use auto extraction option and also check all given extraction option and choose best extraction option.
3) After creating midsurface if getting some errors in geometry then resolve it by using tools in 'Quick edit panel'.
4) After done geometry clean up we need to go for meshing. For that we have to go 'Automesh' tool in '2D' panel.While Perform the meshing keeping in mind that no getting rotating quads and opposite tria elements. we can split different surfaces for getting proper mesh flow.
5) And by 'quality index' tool we can check failing elements and reconstruct it with element clean up tool. The meshing is done manually region-wise using spliting surfaces which helps in getting the proper mesh flow with less tria concentration.
6) We can use reflect option where surfaces are symetrical. for that go to 'Reflect'tool in 'Tool' panel, select elements, axis of rotatin, base point and then hit 'reflect'.
7) After getting porope meshing need to go for thickness assignment. for that first check thickness from original component which is 0.75. then create separate property collector in model tree panel and assign this property to component.
Conclusion :-
- Midsurface extraction of Wheel holder component is created properly. Performed meshing with given quality criteria and having less failing elements for quality criteria.
