Week 8-3D Tetra Meshing Challenge

Model 1:

Aim:

To create a tetramesh for housing component with the following component

Procedure:

Step1.

Import the model and check for any geometrical error

Defeature some surfaces that fail for minimum length error.

Step2:

Initially mesh the surface using 2d tria elements with target size 5mm

Check for minimum and maximum length error

Check for minimum and maximum length error to rectify the max length error use distance option

Go to 3D-Tetramesh option to tetramesh select elements mesh and then tetraremesh

check for tetcollapse and clear those options

Hub:

Geometry clean up on the components

Toggle the small lines which fail for minimum length

Go to 2D automesh trias with target element size 5mm

Check for minimum and maximum length error to rectify the max length error use distance option

Go to 3D-Tetramesh option to tetramesh select elements mesh and then tetraremesh

check for tetcollapse and clear those.

Conclusion:

Thus the housing component meshing was done with 2d to 3d conversion was done with tetramesh 0.15

Model 2:

Aim:

To create a 3D tetramesh option of crank with quick tetra option.

Procedure:

Step1:

Import the geometry and check for geometrical errors

Defeature some surfaces which fails for minimum length error.

Step2:

Go to view- browsers-hypermesh-utility

select the components and then procced and change the elements type as trias only with mesh size 3mm

click on mesh

Check for tetcollapse 0.15 by tetraremesh options

Conclusion:

Thus the crank component was done with quick tetramesh option and check for tetcollapse.

Model3:

Aim:

To create a 3D tetramesh using quick tetramesh/volume tetra option.

Procedure:

Casing1 was meshed with the volume tetra

Central hub was meshed with the quick tetra

Casing2 was meshed with the volume tetra

Hub1 and hub 2 was meshed with the volume tetra

Check for the tetcollapse

Conclusion:

Thus the component was meshed with satisfying the tetcollapse
