Week 8-3D Tetra Meshing Challenge

Aim:

To solve 3D tetra mesh given components.

Objective:

¬To perform different method to solve the solid parts.

¬To give tetra mesh in given components.

Model 1: (Housing hub)

Given CAD:

Given data:

TetraMesh Generation Method: 2D to 3D Conversion

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

Tet collapse: 0.15

Procedure:

¬ Initially import the cad model in hyprmesh.

¬ This method is 2d to 3d coversation.

¬ Check the geomtry clean up.

¬ Now going to mesh 2D components .

¬ Go to 2D - automesh -selected as surface - target value as 5.

¬ Select the surface and give mesh option.

¬ Similarly to the other components.

¬ check the min and max length value in quality issues.

¬ clear all the quality.

¬ Then converted into 3d components.

¬Go to 3D - tetramesh- tetramesh-select element - give mesh

¬2D mesh is converted into 3D mesh components.

¬Similarly to other components.

¬After 3d coversation need th check the quality.

¬Check the tet colapse - check element - 3d - tet colapse - value 0.15 .

¬ if any error available using the remesh option in tetramesh or else manually clear it.

Model 2:

Given CAD:

Given data:

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 3 Units.

Tet Collapse: 0.15

Procedure:

¬ Import the geometry in hypermesh.

¬ Check the geometry any red line are available or not.

¬ In this model no min and max element value.

¬ No need to 2d to 3d conversation#

¬This parts going to mesh directly as a 3d components.

¬ go - 3d - tetramesh - volume tetra - surface - select the surface.

¬Give element value as 3 .

Model 3:

Given CAD:

Giveb data:

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 4 Units.

Tet Collapse: 0.15

Procedure:

¬ There are 4 components in this model .

¬ Going to mesh the components in different method.

¬This components meshed using the volumetetra method.

¬ This part is meshed using voulmetetra method - solid components.

¬Then next part meshed in quick tets method.

¬ Go to view - browse- hypermesh - utility.

¬ select geo- quick mesh - select components - element value - and meshed.

¬ And the final part is mesh using 2d to 2d conversation method .

¬ Previously explain about this method.

¬ check the tet colapse errors and clear it all

¬ Final output of the components.

Conclusion:

¬Learn different method to solve the tetra mesh of 3d components.

¬ Able to clear the tet colapse errors.

¬understand the 3d mesh components.
