Tool Test 1

Tool test 1

Objectives:

• The objective of this project is to performing meshing for Tool test 1 for component1 & Component 2 using the ANSA tool.
• From the given Component, Checking geometrical errors and mesh with given element quality criteria
• Extracting the mid surface from the component.
• After meshing the component the thickness has to be assigned.

Given Quality Criteria Feature:

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

1. Modal

Modal 1: Component 1: Switch panel

Modal 2: Component 2: Floor Panel

2. Clean geometry models

• Now we need to clean up the geometry. When we import the geometries, there are many errors such as topo, triple cons, single cons, cracks between two surfaces etc.
• These can be easily dealt with doing topo at the start. For the other errors, you would need to make a new surface or recreate an old surface.

Clean geometry model 2

3. Mid surfaces of models

• Now we need to create a mid surface of the plastic components. For model A, I used auto mid surface as manual mid surface was taking time and features were also difficult to capture. For the model B, Iused manual mid surfacing using offset function.
• The thickness for both the models is measured.

The mid surfaces of the two models are as follows:

4. Finally we need to mesh and give the quality criteria for the two models. The mesh method used was spot meshing and the element length was 4 mm

The mesh of the two models are as follows:

Learning Outcomes:

• Able to do topological clean-up with no errors.
• Aware of all the quality criterias and quality parameters during mesh generation. Understood about mesh generation and implemented mesh generation for complex geometry

Conclusion:

The giving model 1 & model2 setup is pre-processed successfully, with assembled all parts with FE Mesh that satisfy all quality criteria and thickness to be assigned with the property of the component.

Notes:

The time taken is as follows two models:

• Model 1: 4hrs
• Model 1: 2hrs 40mins
