Project 1 - 2D meshing on the instrumental Panel

OBJECTIVE

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.

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

12 Tria Percentage 15

PROCEDURE

• Open the given model.
• 
• Do topo.Go to geometry checks.
• Select single cons,triple cons,overlapped surfaces,unchecked surfaces,cracks,needle face etc.If any remove them manually or automatically.

• Extract the mid surface using offset, face- middle ,middle curve options.
• Again do topological cleanups
• Remove unwanated cons and nodes which may cause failure of quality.
• Assign PID to different parts as per the thickness.

• Go to mesh deck.Set the quality criteria in the mesh parameters and quality options.
• Mesh the mid surface using batch mesh or manual option.
• Remove the off elements,opposite trias,rotational quads using split,paste,reconstruct,smooth options.

• Go to quality criteria-presentation parameters- select draw shell as solid.
• 

LEARNING OUTCOMES

• Understood how to do topological cleanups and extraxt mid surface using different methods.
• Understood how to do batch meshing and manual meshing.
• Understood how to assign thickness to different PIDs.

RESULT

For the given component, checked the geometrical errors and meshed with the given element Quality criteria. After meshing the component the thickness assigned.

CONCLUSIONS

There are some Failed elements near to Triple CONS or at smaller regions which are bounded by two Triple CONS.
