Week 11-3D Tetra Meshing Challenge

3D Tetra meshing on the given models

Aim: To perform 3D tetra mesh on the given models.

Procedure: Model(housing)

Next step is to defeature some edges which might fail for minimum length quality criteria, like shown below.
Initially Mesh the surface using 2D tria elements
Check for minimum and maximum element size error from and clear the same
Below the image shows there no min and max element size error

Check tet collapse for 0.15, in tools>check elements>3d>tet collapse, fix the errors by tetra remesh or manually by moving the nodes
Below image shows there is no tet collapse error.

Model 2:

Step 1:-

Import the geometry to the software
Look for any geometry error in the cad, this model contains few unstitched edges like shown below
In this model there is no minimum and maximum element size criteria
So used the volume tetramesh method to mesh the model
The given model is surface, so used 3d>tetramesh>volume tetramesh> surface, gave the desired element size and gave tet collapse value in tetramesh parameter
The given model is meshed and fixed all the tet collapse error
Below image shows the final result

Model 3:

Steps carried out :-

Import the model to the software, look for any geometry error
There are 4 different components in this model, mesh each the component in different methods
Casing 1 is meshed using volume tetramesh method
Casing 2 is meshed using quick tetramesh method
Central hub is meshed by 2d tria element and convert the same to 3d tetramesh
Hub will be meshed one side and be reflected to the other side like shown below

CONCLUSION:

Ship work like this
in your own course.
