Week 8-3D Tetra Meshing Challenge

 Aim :

• create 3D tetra meshing 

Objective :

1. Create a Teramesh for Housing component with the following quality criteria.

TetraMesh Generation Method: 2D to 3D Conversion

Elements sizes: Min- 2 Units, Target- 5 Units, Max- 7 Units 

Tet collapse: 0.15

2. For the given model, Create a 3D Tetramesh with the following quality criteria. 

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 3 Units.

Tet Collapse: 0.15

Model-2 

3. For the given assembly model, Create a 3D Tetramesh with the following quality criteria.

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 4 Units.

Tet Collapse: 0.15

Model-3

First Objective :

• first, change the criteria settings such as min element size as 2, max element size 7, target element size 5 tet collapse 0.15
• preferences >> criteria settings 

• then delete the solid and create the 2d mesh with the trial elements 
• 2D >> automesh 

• generate 3d tetra mesh from 2d mesh 
• 3d >> tetramesh then select the 2d elements the create the 3d tetra elements 

• check for elements fails for tet collapse shows 0 

Second Objective :

• first change the criteria for file as per given target elements of 3 units and tet collapse 0.15
• then as we need to create Quick Tetra Mesh/ Volume Tetra Mesh for given component we will not delete the solid.
• we select whole compoenet and create the tetra mesh
• 3D >> tetramesh >> volume tetra
• 

• check for elements which fails for tet collapse shows 0

Third Objective :

• we created the tetramesh using the volume tera for casing1 also for runner 1 and runner 2
• 3d >> tetramesh >> volume tetra with element size 4 as given 

• then we have created the tetra mesh using the Quick tetra mesh.
• view >> browse >> hypermesh >> utility >> Geom/Mesh >> Quick TetraMesh >> select the component

• checked elements fails for tet collapse 0 

Conclusion :

we have meshed all components with 3D Tetra mesh
