Week 8-3D Tetra Meshing Challenge

OBJECTIVE:

TO CREATE A TETRA MESH FOR HOUSING COMPONENT WITH GIVEN QUALITY CRITERIA.

Given Cad Model-1

TetraMesh Generation Method: 2D to 3D Conversion

For geometry clean-up on model following cm are used :-

• add construction line for better mesh flow
• Geom-Quick edit-split surf line
• Geom-Quick edit-split node
• Geom-Quick edit-toggle edge
• Geom-Quick edit-delete surf
• Geom-Quick edit-filler surf

Snap after geometry clean-up :-

• Next step is to create 2D tria element on surface of model
• Quality criteria :- Elements sizes: Min- 2 Units, Target- 5 Units, Max- 7 Units Tet collapse: 0.15

2D - automesh - surface

2D mesh Snap :-

• Convert 2D surface mesh to 3D volume mesh :-

3D - tetra mesh - element

Delete 2D element from model :

Delete - elements - by config - tria3

Final Meshing Model :-

Model :-2 :-

TetraMesh Generation Method: volume mesh

3D tetra mesh - volume mesh

Model 3 :-

TetraMesh Generation Method: Volume Tetra Mesh

Final mesh model :-

Check meshing for Tetra collapse

Final mesh model :-
