Week 3-Meshing of Hood Challenge

                                                                      Week - 3

                                                      Meshing of Hood Challenge

Aim : 
         To work on the Hood model as per the given 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 %	1

Procedure: 
             

•  Imported the given hood model and checked for any missing faces or errors with                   lines.
  
           
• Extracted the midsurface using the Automidsurface , skin offset option. 
• Did the geometry clean up using the autoclean up option. 
• Toogled some lines using the quick edit > toogle lines option to get a good mesh before meshing.
  
  
  
• Used the washer split tool from the quick edit option to give the washer split around the holes. 
• Entered the values for quality critria given.
• Meshed the half midsurface using the auto mesh option as we have a symmetric geometry.
  
• Using the clean up tool such as place node, optimize elements , smooth, split quad, combine trias tools to clear the errors according to  quality criteria given. 
• Used the reflect option to reflect the elements to the other half of the part.

Learning outcomes :

• The quick edit options.
• Meshing option selecting only elements.
• Clean up tools in quality index. 
• Reflect option to copy the mesh to the symmetric side. 
  Conclusion:
                      Obtained the Midsurafced of the hood and meshed the model accordingly as                         per  the given quality criteria
