Week 8-3D Tetra Meshing Challenge

Objective:

• 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

• The minimum length and the maximum length are to be checked only for 2D elements when performing a 2D to 3D Mesh.

  Housing Model

  Coversion of 2D Tria mesh to 3D Tetrahedral Mesh by using Tetra Mesh Pannel:

  Steps to create the Housing fro 2D to 3D Tetra mesh
• Import the model into the GUI.
• 
• Delete the solid in the geomentry by Delete-solids-delete.
• Gemoentry cleanup will be done to the model so that we can toggle the unnecessary lines.
• Now perofoming the 2D operation by mesh Type "Tria" Target Element size as 5units.
• 
• After completeing the 2D mesh the model should clear the Max and Min element Failure.
• Now The model should proferm the 3D mesh from 3D-TetraMesh option.
• 
• In Tetra mesh Select the elements under the Fixed Trias and quards to tetra mesh option.
• After meshing click on the mesh.
• 
• 
• 
• Once the meshing is completed click on the mask option to see the 3D tetra mesh is created.
• 
• 
• 

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

Generating Tetra Mesh using Tetra mesh utility Panel

• Import the Model into the Hyper mesh and clean the geomentry.
• 
• Delete the solid in the model Delete-solid-Delete.
• Click on View-Browzer-hypermesh-utility
• 
• 
• 
• 
• Now select the mesh/Geomentry from the utility panel and tetra mesh.
• In Quick Tetra mesh select the componemts and elements.
• Specify the mesh type " Trais"and mesh size and click on Mesh.
• 
• After completing a surface mesh diagloue would appear click on it.
• Checking the Tet Collapose and remesh if any elements failure takes place.
• complete the mesh by using Quick Tetra mesh.
• 

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

Generating Terta Mesh by uisng volume Tetra Mesh.

• Import the Model into the Hyper mesh and clean thr Geomentry.
• 
• 
• Keep the solid in the model 3D-Tetra Mesh
• 
• 
• 

• Click on volume tetra and select the solids on the model.
• Click the use curvature and use proximity.
• Specify the Min element length and Click on cleanup element.
• checking the Tet Collapose value and remesh and Translate the option to element failure.
• 
• 
• Complete image of the tera mesh by using Volume Tetra Mesh.
