Week 12:Project-1-Meshing of Door Inner Panel Challenge

Objective :- Mesh the model of inner door panel with given quality criteria.

Target Element Length = 4 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	6 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
11	Tria %	10

Procedure :-

1) First we need to import given inner door panel using import option.

2) Defeature all small fillets by using Using the Surf Fillets option in 'defeature' tool. identify and remove surface fillets. By clicking on remove all selected fillets will be removed.

3) Then have to go for Midsurface extraction. Before extracting the mid surface, the thickness of the model is to be known. As the given model is a plastic model, It will have the varying thickness. The thickness can measure using 'f4' key and measure distance between two points.

4) After checking the distance, the mid surface is extracted by using offsetting the surface. for that we have to go 'surface edit' tool in 'geom' panel. go to offset select surface, make duplicate it into cuuernt component, add offset value, check vector direction and then hit offset.

5) Midsurface for ribs :- For midsurface extraction of ribs we can create midline on above and bottom part of Rib and from that lines we can get surface using ruled tool, which is midsurface of ribs

6) After creating the mid surface of all the components we have to go for geometry clean up on the mid surface to get a better mesh flow. for that use quick edit panel. We have to toggle the unnecessary lines and remove free edges. We can split surfaces for better mesh quality.

7) After done geoetry clean up we have to go for meshing. For that go to 'automesh' tool in'2D' panel. Select surfaces one by one and perform meshing on it.

8) After completed meshing remesh or reconstruct some mesh to avoid trias and getting better flow of mesh. then check quality criteria, if any elements get fail for quality resolve it by using clean up tool in quality index or using translate tool.

Final meshed Component

Conclusion :-

1) Successfully extracted midsurface of inner door panel model. performed meshing and satisfied given quality criteria with getting proper mesh flow.
