Week 8-Challenge

3D Meshing:

Elements sizes: Min- 2mm, Target- 5mm, Max- 7mm

Tet collapse: 0.15

1. Create Teramesh for Housing

Importing the model.

• Delete the solids if any exists.

• Surface cleanup is done before 2D meshing.

Creation of Mesh: 2D -- > automesh

• 2D mesh model is created with only trias with the target element size of 5mm, in order to create tetramesh.

• All the min element size are correct and elements with min size less than 2mm are brought to zero.

• All the max element size are correct and elements with max size more than 7mm are brought to zero.

Creation of 3DMesh: 3D -- > tetramesh

• Select the Tetra mesh option.
• Select all the 2D elements to create the tetramesh.

• 3D tetramesh is created.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

Similarly :-

• Manual cleanup is done and component is ready for 2d mesh.
• 2D mesh model is created with only trias with the target element size of 5mm, in order to create tetramesh.

• All the max element size are correct and elements with max size more than 7mm are brought to zero.

Creation of 3DMesh: 3D -- > tetramesh

• 3D tetramesh is created.
• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

2. For the given models, Create 3D tetramesh with 6mm element size.

Model 2-Crank Housing.

Importing the model.

• Model cleanup is done and made ready for 2D mesh.

• 2D mesh model is created with the target element size of 6mm.

• Tetra mesh is created from the 2D mesh.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

Model 3--

Importing the model.

• Taking one component as the current component.

• Deleting the surfaces which are failing for min element length.

• As the deleted surfaces leave free edges, the free edges are to be connected manually.

• Masked and reversed the surfaces to be corrected.

• Joined the surfaces with extend surfaces option.

• Complete manual cleanup is done and the component is made ready for the mesh creation.

• 2D mesh model is created with the target element size of 6mm.

• Tetra mesh is created from the 2D mesh.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

Similarly the rest of the components:

• Complete manual cleanup is done and the component is made ready for the mesh creation.

• 2D mesh model is created with the target element size of 6mm.

• Tetra mesh is created from the 2D mesh.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

• Complete manual cleanup is done and the component is made ready for the mesh creation.

• 2D mesh model is created with the target element size of 6mm.

• Tetra mesh is created from the 2D mesh.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

• Complete manual cleanup is done and the component is made ready for the mesh creation.

• 2D mesh model is created with the target element size of 6mm.

• Tetra mesh is created from the 2D mesh.

• Check all the 3D elements for tet collapse of 0.15 (required criteria).
• If any elements fail, they need to be corrected.

• Model 3 completely tetra meshed image.
