Tool Test 1

Objective: To perform geometry cleanup and extract mid surface and mesh generation by following the given quality criteria for the given switch panel and plastic component.

Quality Criteria:

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:

Model 1:Switch Panel

• Import CAD model
• Perform Topology and check for geometrical errors like triple cons, single cons, needle cons and fix the errors
• The switch panel has various features and thickness is not uniform throughout the model so mid surface needs to be extracted part by part
• Seperate PIDs needs to be assigned for parts with varying thickness
• The options present under Faces in Topo Module buttons are used for extracting mid surface
• Once mid surface is eady, the meshing is done by using best mesh or batch mesh
• Quality criteria and mesh parameters are assigned as given and elements which fails for the quality are observed in hidden mode
• Mesh is reconstructed or regenerated so as to bring off elements and trias to minimum

Model 2: Platic component

• Import CAD model
• Perform Topology and check for geometrical errors like triple cons, single cons, needle cons and fix the errors
• The component is a sheet panel of uniform thickness throughout the body
• Mid surface is extracted by offset command and a property ID is assigned to it and mesh is generated by best mesh option
• Quality criteria and mesh parameters are assigned as given and elements which fails for the quality are observed in hidden mode
• There are so many features present in the given model and the mesh around them needs to be regenerated properly to avoid the quality errors
• Mesh is reconstructed or regenerated so as to bring off elements and trias to minimum

Learning Outcomes:

It is observed that it is necessary to compromise on quality so as to capture featues in mesh generation.

Conclusion:

Mesh is generated for both the switch panel and sheet component models
