Week 8 Challenge

OBJECTIVE:

3D (Tetra) Mesh the attached files assembly according to quality parameters as provided.

PROCEDURE:

3 Files were to be meshed:

1. Housing Assembly:

• There were 2 components inside the assembly.
• Meshed them one at a time.
• First checked if the component is a solid. It was a solid.
• Then deleted the solid and was left with surfaces.
• Cleaned up the surfaces, defeatured some fillets and lines to ensure good mesh quality.
• Created a tria mesh with element size 5. It was a surface mesh.
• Then created tetramesh.
• Ensured that the tetcollapse is above 0.15 for the meshed components.
• Repeated the same process for second component as well.

B. Tetmesh Model

• There was one component inside the assembly.
• First checked if the component is a solid. It was a solid.
• Then deleted the solid and was left with surfaces.
• Cleaned up the surfaces, defeatured some fillets and lines to ensure good mesh quality.
• Created a tria mesh with element size 6. It was a surface mesh.
• Then created tetramesh.
• Ensured that the tetcollapse is above 0.15 for the meshed component.

C. Chassis Assembly

• There were 8 components inside the assembly, symmetrically arranged.
• As the components had some interference, used translate command to adjust the components and ensure there was not interference.
• First checked if the component is a solid. It was a solid.
• Used Quick TetraMesh option from Utilities, with element size set at 6 and created mesh for one component.
• The tetramesh was made but tet collapse was less than 0.15 for many elements.
• Ensured the quality was satisfied using Measure option and edited the failed elements.
• Then organized the elements, by transferring the elements into its respective parent component.
• The same process was repeated for all the components on one end, except for the hub.
• For the hub, the solid was deleted and a surface tria mesh was made.
• Then a volume tetramesh was done using the tria elements.
• Once all components on one side were meshed, they were reflected to the other side using a temporary node placed in the middle as base point.
• The 3D mesh of Chassis Assy is now completed.

LEARNING OUTCOME:

This challenge has helped me learn to perform 3D Mesh, as well as improve my current meshing skills. 3D Mesh is completely new to me and I have now learned a new approach to mesh components

RESULT:

The given 3 models were meshed according to the given quality criteria.
