SWITCH PANEL & 2D SURFACE MESHING

Objective:

To create 2D meshing on Switch Panel & Component model as per the quality criteria and assigning thickness to the multiple objects in the model by using ANSA

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

Methodology:

• Geometrical clean-up
• Mid surface Extraction
• Meshing as per the Quality criteria
• Thickness assigning to the model

Cad model: To get clean model need to perform the topology and length perimeter before going for geometrical clean up

Geometrical cleanup:

this error (concave and convex) is not cleaned properly

After geometric clean-up

Extracting Mid-Surface

Extracting mid surface manually using middle but it produced damaged surface, so using offset command extracted manual mid surface here.

Auto mid-surface extraction through casting but it generated distorted elements in the model

Manual mid- surface ------Faces- >Offset - >Mid-surface

MESHING:

Before going to mesh the model we need to update the quality criteria and mesh quality as per the given quality data for the bottle cap.

We need to choose the following details to get proper or smooth mesh.

Shell to solid

• Mixed elements
• Ist order
• Type of mesh: best

Outcomes:

• Able to do the geometrical clean-up
• Mid-surface extraction is done
• 2d meshing

Conclusion: 2D meshing for switch plane & Component is created after the geometrical clean up and also assigned thickness to the model using ANSA.
