Week 8-Challenge

Objective:

1)To create tetramesh for housing component.

2) First clean the model for surface fillets and edge fillets.

3)Delete all the fillets bellow the given range.

4) To mesh the geometry go to 3D mesh-volume tetra-define the element size-mesh.

5) First mesh the hub component.

6)Similarly repeat the above procedure for housing.

(B) Open the model2 and mesh it with above procedure.

(C) Chassis assy:

1)Import the model.

2)Delete the unwanted components.

3)Clear the geometry by using defeature option.

4) Now mesh the geometry first by using 2D-Automesh-Tria elements-Enter element size-Mesh.

5)Then go to 3D-tetramesh-Enter the tetra parameters and mesh.

6)After meshing to check element size and tetra collapse go to tools-check elements.

7) Mesh all other remaining components by following above procedure.

8) Manually change the length or height of the elements to overcome tetra collapse.

9) After meshing whole assy

10)As the model axis system is symmetrical hence reflect the elements by using tools-reflect-elements-duplicate.

11)then select the axis of reflection and base point.

Conclusion:

1)This tutorial helps to create tetras in complex geometry.

2) Geometry cleaning is very important step to achieve better tetra meshing.
