Week 6-Meshing of Hood Challenge
Objective
Follow the below-mentioned quality criteria, mesh the component given below and assign thickness:
Target Element Length = 5 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 | 8 Units |
| 7 | Min angle Quad | 45 |
| 8 | Max angle Quad | 135 |
| 9 | Min angle Tria | 20 |
| 10 | Max angle Tria | 120 |
| 10 | Tria % | 10 |
CAD MODEL
Procedure
- IMPORT MODEL
- TAKE AUTO MID SURFACE GEOM>MIDSURFACE>AUTO MIDSURFACE(SWEEP+OFFSET +PLANE)
- DO GEOMETRY CLEANUP
- TOGGLE GEOM>QUICKEDIT>TOGGLE/PROJ/
- GEOM>POINTS EDIT>REPLACE
- PATTERN TRIA DOESNT HAVE A DIRECTION,(EQUILATERAL TRIANGLE),try avoid it
- input quality criteria
- preferences>quality criteria settings
- mesh the model using tools like2D> auto mesh,remesh,quality index
- quality index>smooth ,split,combine tria,swap etc
- 2D>edit element >split>points,(to split quads)
- tools>translate to clear warpage issues /use f10 and check element failure like warpage
- to check element quality criteria press f10
- USE TRANSLATE OPTION TO CLEAR WARPAGE IF PRESENT TOOLS>TRANSLATE>SELECT NODE,THEN N1,N2,N3
- delete surface and perform meshing if geometry is symmetric
- DELETE UNNECESSARY HOT POINTS
- reflect the symmetric portion after meshing is done
- TOOLS>REFLECT>ELEMENTS>SELECT ALL ELEMENTS>DUPLICATE ALL SELECTED ELEMENTS>SELECT N1,N2,N3, AXIS OF REFLECTION --> REFLECT
- STITCH THE REFLECTED PART TO ONE ANOTHER
- TOOLS>EDGES>ELEMENT>dipslayed>input tolerance less than min length>preview equilance>equivalence>delete edge> repeat the process
- use 2d>replace >midpoint option to stitch edges manually
- f7 and allign nodes at edges if necessery, n1,n2,n
- save model
observation
The model has been meshed with given quality criteria
