Week 4

Objective:-

Mesh the given component using quality criteria and also assign the thickness to the geometry. For the given component check for geometrical errors and elemental errors.

Quality Criteria:-

S.No	Quality Criteria	Value
1	Target/Average length	1
2	Minimum Length	0.5
3	Maximum Length	3
4	Aspect	3
5	Warpage	15
6	Skewness	45
7	Jacobian	0.7
8	Minimum Quad Angle	45
9	Maximum Quad Angle	135
10	Minimum Tria Angle	30
11	Maximum Tria Angle	120
10	Tria Percentage	15

Procedure followed:-

Import the model.

Geometry cleanup for any discrepancy in the model.

After geometry cleanup, mid-surface each and every part of the component individually, and also assign thickness of each component according to the parent model.

Post midsurface, check for geometry irregularities using check geometry command and if any irregularity persists, cleanup the geometry.

After geometry cleanup and before meshing the component we have to assign the Quality criteria, and also assign the mesh parameters.

Now mesh the parts of the component one by one.

Meshing is to be checked for any irregularity and if any discrepancy in the elements, cleanup the elements using various commands we have with us. In our model I have used, swap, join and delete command at most.

Also The major contribution for cleaning up the elements is of Reconstruction of elements.

Conclusion:-

The final model obtained is attached below,
