Week 8-3D Tetra Meshing Challenge

1. Steps to perform TetraMesh Generation Method (2D to 3D) Conversion For Housing Model:

• Select any model to perform the operation.

Component 1.0:

• Make the component 1 as the current component.
• Delete all the solid entities from the component.

• Cleanup the geometry removing the unwanted surfaces and toggling the unwanted lines.
• Mesh the component w.r.t the tria elements considering all the quality criteria.

• Opt 3D>Tetramesh>Tetramesh>Select the elements>Mesh and check the elements in By Component view by conisdering all the parameters such as min max and tet collapse values.

Component 2.0:

• Make the component 2 as the current component.
• Delete all the solid entities from the component.

• Cleanup the geometry removing the unwanted surfaces and toggling the unwanted lines.
• Mesh the component w.r.t the tria elements considering all the quality criteria.

• Opt 3D>Tetramesh>Tetramesh>Select the elements>Mesh and check the elements in By Component view by conisdering all the parameters such as min max and tet collapse values.

2. TetraMesh Generation Method using Quick Tetra Mesh.

• Import the Geometry.

• Delete the solid from the model.

• Cleanup the model.
• Go to View>Browser>Hypermesh>Utility>Geom/Mesh>Quick Tetra Mesh.
• A Box appears in the Tab bar.
• Select the component, enter the mesh size as 3 units, minimum element size as 1 and Mesh Type as Trias Only then Mesh
• Click on ok after that you get after the 100% Attempt
• You will get a Quick_Tets component in which you will have all the Tetra elements.

TetraMesh Generation Method using Volume Tetra Mesh.

• Import the model.

• Perform Geometric cleanup.
• Select the first component and make it as the current component.
• Go to 3D>Tetramesh>Volume Tetra>solids>displayed>Element size to be "4" and check in the Use curvature and Use proximity
• Go to Tetramesh Parameters, Enter Tet Collapse value "0.15"

• Check for tet collapse failure, if founded, Go to 3D>Tetramesh>Tetra remesh>Select the failed elements>remesh or Tools>Translate>select nodes>Select vectors>provide Magnitude>Translate.
• Similarly follow the procedure for all the other components.
