Week 8-3D Tetra Meshing Challenge

Aim :

To mesh the given component using Tetramesh and to check for the tet collapse in the Hyperworks software.

Objective :

To mesh the components in 3D meshing by using Tetramesh option and to satisfy the given tet collapse value 0.15.

Procedure :

1. Import the model to the graphical workspace and select the profile as RADIOSS.
2. To check the component for geometry clean-up.
3. To apply mesh on the component by selecting 3D Menu – Tetramesh.
4. In tetramesh menu we have different options like tetramesh, tetra remesh, volume tetra, tetramesh parameters and refinement box.

Model (1) :

In this model it is asked to mesh the given component in 2D tria elements with few quality criterias like min size and max size.

After satisfying the quality criteria we use Tetramesh option in 3D menu and apply the mesh over the 2D meshed elements and it will capture the complete structure of the given component.

By doing in this method of meshing the component we will have more control over the component and while applying 2D to 3D we can reduce the tet collapse element values.

Given component :

Worked component :

Model (2) :

In this model it is ased to apply Tetramesh on the given component and to check for the tet collapse rate.

So here we directly apply Tetramesh by using the option called Volumetetra and select tha component even it is a solid or surface component we can apply mesh.

After applying mesh we use check elements menu 3D in that we check for the tet collapse.

In case of any elements found in tet collapse we do tetra remesh and reduce the tet collapse.

Given component :

Worked component :

Model (3) :

In this model we got the component which is already meshed by using Tetramesh and have some geometrical errors so it is attached as it is given. As I tried to work on the model it has some issues in the geometry of the given model so had a review on that to confirm it.

Given component :

Result :

The meshing of given components is meshed using Tetramesh successfully using Hyperworks software and it also satisfies the given criterias.

The masked components is attached for the reference below.
