Week 12:Project-1-Meshing of Door Inner Panel Challenge
AIM :
- To extract mid-surface, geometry clean up and create the shell (two dimensional) mesh for the given side door inner panel according to the given quality criteria by using HYPERMESH.
QUALITY CRITERIA REQUIREMENT:

PROCEDURE:
- First, import the side door inner panel model into HyperWorks.

- Since there are many ribs with surface fillets, it is difficult to create their mid-surfaces.
- So, these fillets are removed or defeated by going to Geometry > defeature >surf fillets.
- Then specify minimum radius, maximum radius, select surfaces and click find.
- The fillets are shown as highlighted, then click remove to remove the fillets.

- Clean up the geometry of the components for obtaining better mid-surface.
- Now, after checking the thickness at various points of the components by Geometry > distance > two points, it is found that the component has varying thickness.
- So, manual mid-surfacing is done by going to Geometry > surface edit > offset.
- Then, select the surface and duplicate it, specify offset thickness and click offset and the mid surface is created.



- There is also a cylindrical surface which can be done in the same procedure


- After extracting the mid-surface, perform the geometry clean up.
- Then, the mesh can be created by 2D > automesh > size and bias.
- Then, assign element size, mesh type , select surface and click mesh.


- The obtained mesh fails for quality criteria which can be corrected by remeshing with 2D > rebuild mesh ad select edit criteria.
- A window is opened where quality criteria requirements can de given. Then, select the elements and click rebuild.
- If the mesh still fails select the elements and remesh it.

- Quality critiria result

Assign thickness:
- Since there are surfaces and many ribs with varying thickness, arrange the elements with same thickness to the same component by Tool > organize,
- select the elements and click move.
- Then create property cards for all the thickness and assign it to the respective components.



RESULT:
The given is meshed property with the given quality criteria requirements and the correct thickness is assigned the respective elements.
