Week 12:Project 2-Meshing of Rear Wheel Holder challenge

AIM :

to mesh the given component with the mentioned quality criteria and assign thickness.

OBJECTIVES :

1. generate the mid surface for the given rear wheel holder.

2. make proper geometric clean up for the component.

3. mesh the component as per the given quality criteria.

PEOCEDURE :

1. import the model in to the hypermesh through the option, import model - import geometry - file type - IGES - select file - import.

2. visualy inspect the rear wheel holder for any missing surfaces,free edges and non manifold lines.

3. make the model in to the wire frame mode and enable suitable visualization options and find out all the free edges and missed surfaces.

4. fill all the missing surfaces and free edges by using filler surfs option and ruled option.

5. for filling free edges by filler surface option,go to quick edit - filler surfs - select the free edges.

6. for filling edges by ruled option , go to surfaces - ruled - select line.

7. also use the toggle edge option by going through, quick edit - toggle edge - apply tolerence - select free edges and clear it.

8. go to edge edit and replace unwanted free edges.

9. after geometric clean up create the mid surface of the component by going through, mid surface - auto mid surface - extraction options - offset - auto extraction - select surfaces - extract.

10. after taking midsurface then go to meshing.before meshing toggle the ines that are fail to the minimum length.toggle all the unwanted lines and prepare a neat geometry to mesh.

11. after that apply the given quality criterias like aspect ratio,warpage,tria percentage..etc.for that go to, preference - criteria file settings - 2D - apply quality - ok.

12.then select the surfaces and mesh by going through 2D - automesh - srfaces - mixed - mesh.

13.mesh all the component and clear all the quality errors.rebuild the mesh for getting etter mesh flow and cear quality.for that go to, 2D - rebuild mesh - slect elements/surfs - edit parameters - rebuild.

14.by going through quaity index - clean up tools - smooth/place node/swap edge/node optimize/element optimize..etc clear all the quality criterias and improve the mesh.

15.also use replace node,combine,align options to improve the quality of the mesh.

16.dissassosiate the model by going through preference - topology revision options - dissassosiate for making changes in the mesh.

17.remove unwanted trias and improve the mesh.

18. assign thickness for the component by creating a property card.

19.clear all the quality criterias given and finish the work.

RESULT :

meshed the given component with the mentioned quality criterias and assigned thickness.also finished the work neatly.
