2D Meshing of automotive side door component

Aim:

To manually extract the midsurface of the given geometry, clean up the midsurface for meshing and mesh it according to the quality criteria then assign the thickness to different parts of the geometry.

Procedure:

1. Import the geometry into hypermesh using import option.

2. Cut the geometry into 4parts for easy editing and fixing of the geometry using surface edit oprion from geometry menu.

select all the surfaces and change the axis in which you want to cut the model and select the base point where you want the cut.

3. Seperate the surfaces according to the cut lines by moving them to different component using organise option .

4. check for free edges and fix the geometry accordingly.

5. Defeature the fillets present on the ribs manually if the fillet size is less than 2mm.

6. creat a seperate component for midsurface, switch it as current, use offeset option from surface edit to off set the surface to get the midsurface. dublicate the surface to current component befor offset.

before midsurface extraction.

Midsurface of the part.

7. Use the surface edit to trim the intersecting surfaces and delet the extra surfaces to get the a clean surface.

8. repeate the same foe other components to extract the midsurface and clean up the surface for meshing.

midsurface of the model ready to mesh.

9. Use automesh option to mesh the component and check for quality.

10. remesh the elements which are failed , use quality index for minor elament optimization to elements which are not near intrecate lines.

11. seperate the elements and surfaces of different thickness into different components.

12. create property for different thickness card and material card for the model.

13.assign the property card according to the thickness of the master component.

Meshed part.

Elements quality check.

2D detailed representation.

Conclusion:

In this project the given model has been analysed and fiexed to generate a midsurface and it is meshed according to the quality index provieded, thickness to different components is added accordingly.
