Week 8-3D Tetra Meshing Challenge

AIM

Create a Tetramesh for given component with the given quality criteria

COMPONENT 1

COMPONENT 2

COMPONENT 3

PROCEDURE

For the given first component there are two parts available I seperately cleanedup and created mesh for the given component

COMPONENT 1

1.CLEANUP

Cleanup is the process of toggeling unwanted geometry lines and repairing surfaces so as to eliminate elemental failure

while component is meshed

Given criteria for the first component is target element size is 5 and minimum and maximum sizes are 2,7 and tet collapse as 0.15

2.MESHING

There are two methods of tetra meshing the component

1.converting 2D shell mesh to Tetra mesh

2.Quick tetra mesh

I used method 1 to mesh this component

1.converting 2D shell mesh to Tetra mesh

for the component i meshed the component with tria elements so as to create tetra elements

2D-->AUTOMESH-->TARGET ELEMENT SIZE(5)-->ELEMENT TYPE(TRIA)-->SURFACES MESH

TETRAMESH

By using the shell elements on the component i created tetra elements by using 3D mesh pannel present in hypermesh

First i updated the tetramesh parameters for the given parameters

3D-->TETRAMESH-->TETRAMESH PARAMETERS-->TETRA MESH-->ELEMENTS-->MESH

Tetra elements are created i need to check for Tet collapse and failed elements are cleared by using Tetra Remesh

3D-->TETRAMESH-->TETRA REMESH-->ELEMENTS-->REMESH

Elements failed for tet collapse are 0(0.0%)

COMPONENT 2

Given target element size for this component is 3 units

I used quick tetra mesh for 3D meshing this component

VIEW-->BROWSERS-->HYPERMESH-->UTILITY-->GEOM/MESH-->MESH TOOLS-->QUICK TETRAMESH

The elements failing for tet collapse are 0(0.0%)

COMPONENT 3

Created tetra mesh by using method 1 i.e; using 2D elements created on the surfaces of the component

elements failing for tet collapse are 0(0.0%) for the above component

elements failing for tet collapse are 0(0.0%) for the above component

elements failing for tet collapse are 0(0.0%) for the above component
