Week 8-3D Tetra Meshing Challenge
Objective
Model 1: - Create a Teramesh for Housing component with the following quality criteria.
- Tetra Mesh Generation Method: 2D to 3D Conversion
- Elements sizes: Min- 2 Units, Target- 5 Units, Max- 7 Units
- Tet collapse: 0.15
Model 2: - Create a 3D Tetramesh with the following quality criteria.
- Tetra Mesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh
- Target Element size: 3 Units.
- Tet Collapse: 0.15
Model 3: - Create a 3D Tetramesh with the following quality criteria.
- Tetra Mesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh
- Target Element size: 4 Units.
- Tet Collapse: 0.15
Solution
Step 1: - Cad model images.
Step 2: - Meshing: -
Model 1 was meshed using 2D to 3D mesh.
Model 2 was meshed using quick tetra mesh.
Model 3 was meshed using quick tetra mesh & volume tetra mesh.
Step 3: - Checked for tet collapse.
Step 4: - Tet collapse was resolved by using tetra re-mesh option.
The remaining tet collapse was resolved using translate option.
Step 5: - Results and Final Images.
Step 1: - Cad model images.
