Project 2 - 2D meshing on the instrumental Panel

AIM

For the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned.

Write a detailed report on your meshing process and also mention which method you used to extract the mid-surface along with the reason.

S.No	Quality Criteria	Value
1	Target/Average length	4
2	Minimum Length	2
3	Maximum Length	6
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

OBJECTIVE

check for the geometrical errors and mesh with the given element Quality criteria

After meshing the component the thickness has to be assigned

BODY OF CONTENT

• Importing the component
• 
• perform topo to stitch surfaces
• perform geometric check and correct errors
• refine macros and perimeters to targetted length
• input quality criteris

• CASTING METHOD

  • perform automatic mid surface by using casting/allign manager
  • • 
    • 
    • mid surface and meshing is generated by casting
• • make sure no area is empty and if so assign it with(middle ,plane,,,)(mandatery)
  • check mid surface is captured properly w.r.t parent geometry
  • in align manager -->perimeter-->select proper faces for proper definition of parts
  • 
  • perform meshing operations to get a good mesh like swap,split, reconstruct ,paste,collapse etc
  • make sure to satisfy quality criteria
  • use curves , cones2curves to capture features 

• 

• 1) Dog house in this model should be captured as "Cross pattern" in Mid surface since dog houses are solid (Hollow from inside) and is not having any thickness. (Refer the below image to understand how to capture the Dog houses which are solid(Hollow) )
• 
• use imprint to capture cones of parent surface  onto midsurface like above

• assign thickness by using auto thickness assignment thickness-->convert as we use casting method

• 

above is the final model

Conclusion

Mid surface of all components has been made and meshing has been done

Trias has been kept to minimum to avoid failure due to stress concentration

Quality criterias are all satisfied as per given and off elements are avoided wherever possible
