Week 8-3D Tetra Meshing Challenge

MODEL 1:

OBJECTIVE:

To create a tetramesh for the given housing component by 2D to 3D conversion method.

CAD MODEL:

PROCEDURE:

• This model consists of 2 components. So, tetrameshing of the components are done separately.
• First, the solids are deleted by delete command.
• Now the first component is selected for meshing.

• For 2D to 3D conversion method, first 2D meshing (only trias) is done on the component.

• Now the elements are checked for quality criterias. i.e min and max size of elements.

• Now tetra meshing is done by selecting the created tria elements.

• Now the tetramesh elements are checked for tetcollapse.

• As the tetcollapse failure is 0%, we have successfully completed the meshing.
• Now we have to perform the same operations for the second component.
• For the second component, geometry cleanup is done before meshing.

• Now tria elements are created and then converted into 3D tetra elements as mentioned above.

FINAL MODEL:

RESULT:

The given model is successfully meshed by the 2D to 3D conversion method and according to the given quality criteria.

MODEL 2:

OBJECTIVE:

To create a tetramesh for the given housing component by quick tetra mesh or volume tetra mesh method.

CAD MODEL:

PROCEDURE:

• We have chosen quick tetra mesh option for this meshing
• Quick tetra mesh panel is opened and the given parameters are entered.
• Then the meshing of the component is done.

• Now the elements are checked for quality criterias. i.e tetcollapse.
• The failed elements are selected and remeshed through tetra remesh option.

• Now the tetramesh elements are again checked for tetcollapse.

• As the tetcollapse failure is 0%, we have successfully completed the meshing.

FINAL MODEL:

RESULT:

The given model is successfully meshed by quick tetra mesh method and according to the given quality criteria.

MODEL 3:

OBJECTIVE:

To create a tetramesh for the given housing component by quick tetra mesh or volume tetra mesh method.

CAD MODEL:

PROCEDURE:

• This model has 5 components. so meshing of the individual components is done individually.
• First we wwill be doing volume tetra meshing of the first component
• We have chosen volume tetra mesh option for this meshing
• Then the meshing of the first component is done.

• Now the elements are checked for quality criterias. i.e tetcollapse.
• The failed elements are selected and remeshed through tetra remesh option.

• Now the tetramesh elements are again checked for tetcollapse.

• As the tetcollapse failure is 0%, we have successfully completed the meshing of the first component.

• Next we will be doing volume tetra meshing using the surface of the first component
• We have chosen volume tetra mesh using surface option for this meshing because the component has some interference in the model.
• The interference of the model is corrected and the volume tetra meshing is done.

• Now the elements are checked for quality criterias. i.e tetcollapse.
• The failed elements are selected and remeshed through tetra remesh option.
• Now the tetramesh elements are again checked for tetcollapse.

• As the tetcollapse failure is 0%, we have successfully completed the meshing of the second component.
• The same procedure is repeated for the other 3 components.

FINAL MODEL:

RESULT:

The given model is successfully meshed by quick tetra mesh and volume tetramesh method and according to the given quality criteria.
