Week 8-3D Tetra Meshing Challenge

OBJECTIVE:

To create tetra mesh for given componenet under given criteria.

GIVEN CRETERIA:

For Model 1

TetraMesh Generation Method: 2D to 3D Conversion

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

Tet collapse: 0.15

For Model 2

Create a 3D Tetramesh

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 3 Units.

Tet Collapse: 0.15

For Model 3

Create a 3D Tetramesh

TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

Target Element size: 4 Units.

Tet Collapse: 0.15

SOFTWARE USED:

Hyper Works 2021

GIVEN MODELS:

MODEL 1.1 MODEL 1.2

MODEL 2

MODEL 3

PROCEDURE:

• MODEL 1:

• For model 1 we need to clean the geomentry for prevent from minimum size failure.
• Delete(F2) the solides before doing 2D mesh

Tool→delete

• Then do 2D mesh(F12) for the component

2D→auto mesh

• Check the element failure(F10) for the mesh

Tool→check elements

• Do 3D tetra mesh for the 2D mesh

3D→tetra mesh

• Check the element failure(F10) for find tet collapse

Tool→check elements

• Then mask(F5) the failed 3D elements and clear the tet collapse

Tool→mask

MODEL 1.1

MODEL 1.2

• MODEL 2:

• Do 3D tetra mesh using Quick Tetra Mesh

Utility→Geom/Mesh

• Give mesh size then select the component give mesh
• Check the element failure(F10) for find tet collapse

Tool→check elements

• Then mask(F5) the failed 3D elements and clear the tet collapse

Tool→mask

MESHED COMPONENT AFTER MASK THE SOME 3D ELEMENTS

• MODEL 3:

• Do 3D tetra mesh using Volume Tetra Mesh

3D→tetra mesh

• Give mesh size then select the component give mesh
• Check the element failure(F10) for find tet collapse

Tool→check elements

• Then mask(F5) the failed 3D elements and clear the tet collapse

Tool→mask

MESHED COMPONENT TET COLLAPSE

RESULT:

3D Tetra Mesh is completed for given models under given criteria succesfully.
