Hypermesh purojeet

Objective: To mesh the hood of a car according to the quality criteria given

Procedure:

1. A new Opti struct file was opened in Hypermesh, hood geometry was imported, all the solids were deleted from the component.
2. Separate mid surfaces were created for the all the components, the mid surfaces were checked for defects and geometry clean up was done
3. First 2D meshing was done on the smaller parts latch and both hinges, remeshing was done on the parts where ever it was required.
4. The outer panel of hood is a symmetric part so it was dived into to equal halves using split surface by node, one half of the outer panel is meshed part by part by dividing the whole surface into parts which are almost rectangle as Hypermesh creates better mesh when given rectangular geometry, the whole mesh was reflected to the other side of the outer panel using reflect option from tools window.
5. The inner panel is also a symmetric component so it was also divided into two parts one part was meshed with 2D elements according to the criteria and the whole mesh was reflected to the other side of the panel using reflect option. The part was checked for the element failures and re meshing was done where ever necessary.

Results:

2D mesh of the latch

2D mesh of the left and right hinge

2D mesh of outer panel of hood

2D mesh of inner panel of the hood

All meshed components together

Conclusion

By completing the challenge, learned the method of 2D meshing sheet metal components like car hood etc
