Week 8-Challenge

Aim:

To create tetramesh for the given models.

Methodology:

• Import the model.
• Clean up the geometry.
• Mesh the model with given criteria.

Introduction:

A chassis is main component in vehicles. All the parts are mounted on the vehicle chassis.It is a load bearing framework of an artificial object.

Procedure:

Model 1:

• Import the geometry from the download folder.

figure-1( import part 1)

Figure-2 (import part 2)

• Clean up the geometry by deleting the unwanted lines.
• Mesh the model surface by surface with given quality criteria.
• Solve the errors if any.
• Go to 3d panel, click on “tetramesh”.
• Select the model and set the quality criteria in “tetra parameters”.
• Go to tetamesh panel, select the model again and click on “mesh”.
• Check for the tet collapse, if any and clear them.

Model 2:

• Import the model from the download folder.
• Delete the solids of the model.

Figure-5 (Import the model)

• Click on “view”,select the “hypermesh”, in that click on “utility”.
• Utility menu bar is displayed in tab bar.
• Select “geom/mesh”, click on “quick tetra”.
• Select the component, set the element size value.
• Select the mesh type and click on “mesh”.

Model-3:

• Import the model and clean up the geometry.

Figure-9 (import the model)

• Delete the half part of the geometry.
• Keep the solids, select 3d and click on tetramesh.
• Click on volume tetra and select the solid.
• Specify the element size as per given quality criteria.
• Tick on clean up elements.
• Click on “mesh” for volume tetramesh.

Learning outcome:

Got knowledge on 3d meshing process and types od 3d meshing

1. Tetramesh
2. Quick tetra mesh
3. Volume tetramesh.

Tools like

1. Tetramesh
2. Tetra remesh
3. Tetra parameters

Result:

The given models are meshed with different types of 3D meshes.
