Week 6-3D Tetra Meshing Challenge

Aim:

Tesh meshes the above three components according to the given quality parameters.

Procedure:

1. Model 1:
   
   For model 1, quality criteria are Elements sizes: Min- 2 Units, Target- 5 Units, Max- 7 Units Tet collapse: 0.15
   • Imported the geometry.
   • There are two geometries, meshed one by one.
   • surface cleared, lines separation of less than 2 units is removed.
   • 2d Auto meshed the surfaces with the target length of 5 units.
   • While checking the min and maximum are failing, so re-meshed the quality by using the tetra re-mesh option. After so many min length is cleared. But the maximum length is not clearing I created nodes and deleted the elements and also created mid node between the larger length nodes. and created tetra manually.
   • 
   • Finally saved the file as Model-01.hm
   • 
2. Model 2:
   
   • 
   • For the given MODEL 2, Create a 3D Tetramesh with the following quality criteria. TetraMesh Generation Method: Quick Tetra Mesh/ Volume Tetra Mesh

     Target Element size: 3 Units.

     Tet Collapse: 0.15

   • Surface cleared the 2d auto-meshed with a target length
   • Cleared the 2d min length below 0.5. In order to get good quality mesh while building the tetra.
   • Created the tetra and cleared the quality by using the tetra re-mesh option. Only tet collapse quality is needed to maintaine here.
   • 
   • Finally I saved the file as Model-02.hm
3. Model 3
   • 

   • Quick Tetra Mesh/ Volume Tetra Mesh

     Target Element size: 4 Units.

     Tet Collapse: 0.15

   • Meshed individually 4 geometries.
   • Surfave cleared.
   • First created 2d and converted to tetra.
   • While checking geometry similarity, I found that the below two geometries are the same except one model has no holes in it. So I completed one geometry and reflected to the opposite geometry and filled the hole with tetra elements.
     
   • While meshing below geometry, surface is intersecting each other so after building I moved 2d elemts little above to create tetra.
   • 
     
     
   • So that region protection is neglected.
   • 
   • The below geometries are matching but both are not in the same orientation.
   • 
   • I completed the mesh and reflected it and rotated it to get in the same orientation as the second geomtry.
   • Finally, I saved the file as Model-03.hm
   •
