Week 4- Meshing of Backdoor Challenge
Aim:
to take the mid surface and mesh it.
Provided below are the quality parameters that you have to follow.
Target Element size - 5 Units
| S.N | Quality Criteria | Value |
| 1 | Aspect Ratio | 5 |
| 2 | Skewness | 45 |
| 3 | Warping | 15 |
| 4 | Taper | 0.5 |
| 5 | Min. Length | 3 Units |
| 6 | Max. Length | 7 Units |
| 7 | Min angle Quad | 45 |
| 8 | Max angle Quad | 135 |
| 9 | Min angle Tria | 30 |
| 10 | Max angle Tria | 110 |
| 10 | Tria % | 15 |
the mesh should be proper by following this quality parameters.
Procedure:
Backdoor panel is provided.open the hypermesh and import the model.
the model is sheet metal component with features and hemmings.

the image above is the parent component.
half of the component id removed because of symmetry.
seperate out the model into three parts and name it as comp1,comp2 and comp3.
now take each part seperately,take mid for it one by one.
now take comp1 and clean it up and toggle the unwanted lines.
then we can see the symmetry of the component.

the above pasted image is the image of the comp1 mid.

this image is the comp2 mid.

this is the comp 3 mid.
because of the symmetry of the component, one side is deleted.
now clean it up the mid.
mesh each and every part of midsurface.
check for any quality errors if there is any quality error clean it up.

the quality should be inserted in criteria file before meshing.



the above pasted images are images after meshing and reflecting the mesh.
each and every parts of mesh must be pasted so there will be continuity.
