Week 8-3D Tetra Meshing Challenge

AIM:- 3D Tetra Meshing :-

OBJECTIVE:-

1. Create a Teramesh for Housing component with the following quality criteria.

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

Tet Collapse: 0.15

2. For the given model, Create a 3D Tetramesh with the following quality criteria.

Target Element size: 3 Units.

Tet Collapse: 0.15

3. For the given assembly model, Create a 3D Tetramesh with the following quality criteria.

Target Element size: 4 Units.

Tet Collapse: 0.15

OBJECTIVE 1:

Create a Teramesh for Housing component with the following quality criteria.

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

Tet collapse: 0.15

Import the given model and check for any geometry error

In this model there are few missing surface like shown in the below image

Houshing model:-

Fill the surface by Surface option or quick edit> filler surface option, like shown in below image

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 quality

.Tet collpase = 0.082475

Mask

OBJECTIVE:-2

.For the given model, Create a 3D Tetramesh with the following quality criteria.

.Target Element size: 3 Units.

.Tet Collapse: 0.15

model 2

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

.Tet Collapse = 0.75434

Objective:-3

.For the given assembly model, Create a 3D Tetramesh with the following quality criteria.

.Target Element size: 4 Units.

.Tet Collapse: 0.15

.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

.Check quality

.Tet collapse = 0.073236
