Week 8-3D Tetra Meshing Challenge

AIM: To perform 3D tetra mesh on the given models

PROCEDURE: 

 Model 1(Housing)
   

 Step 1:-

• Import the given model and check for any geometry error

To clean the geometry by removing free edges, separate the free edges by visualization toolbar
Select view as Free edge, change geometry color mode By Topo, and as Wireframe geometry 

From Quick edit > Fiiler surf Option is done to cover the surface of the geometry 

 Step 2:-

•  Next step is to defeature some edges which might fail for minimum length quality criteria, like shown below

• Initially Mesh the surface using 2D tria elements

• Check for minimum and maximum element size error from and clear the same
• Below the image shows there no min and max element size error

Step 3:-

• Perform 3D tetramesh using the 2D tria elements, 3D>Tetramesh>select all the elements

• Check tet collapse for 0.15, in tools>check elements>3d>tet collapse, fix the errors by tetra remesh or manually by moving the nodes
• Below image shows there is no tet collapse error

MODEL 2

OBJECTIVE:

GENERATE THE VOLUME TETRA MESH ON THE GIVEN COMPONENT.

CAD MODEL WITH IMAGE:

Look for any geometry error in the cad, this model contains few unstitched edges like shown below

PROCEDURE WITH REQUIRED IMAGES:

1. DO THE GEOMETRY CLEAN AND SET THE CRITERIA REQUIRED IN CHALENGE.

2. THEN DO VOLUME MESH AND FIND THE TET COLLAPSE.

3. DO REMESH IF ANY FOUND

TETRA MESHING OF TURBO CHARGER:

OBJECTIVE:

TO DO VOLUME TETRA MESH ON THE GIVEN COMPONENT WITH NO TET COLLAPSE.

CAD MODEL IMAGE:

PROCEDURE WITH CAD MODEL IMAGE:

1. DO VOLUME MESH SEPERATELY FOE EACH COMPONENT.

2. AND CHECK FOR THE TET COLLAPSE.

3. CLEAN UP IF ANY FOUND.

RESULT WITH FIANL IMAGE:

THUS THE TURBO CHARGE ASSSEMBLY IS SUCCESFULLY FINISHED VOLUME TETRA MESHING.
