Week 8-3D Tetra Meshing Challenge

AIM : 

      To perform 3D Tetra Mesh on the given model.

PROCEDURE : 

Model 1 : 

• Import the given model and check any geometry error.

• In this model there are few missing surface . Fill the surface by QUICK EDIT > FILLER SURFACE OPTION.

• Next step is to defeature some edges which might for minimum length quality criteria
• Initially mesh the Surface using 2D tria elements . 

•    Check for minimum and maximum element size error from and clear the same.

• Below image shows there no MIN and MAX elements size error.

• Perform 3D Tetra mesh using the 2D tria elements. 3D>TETRA MESH>SELECT ALL THE ELEMENTS.

• Check Tet Collapse for 0.15, in TOOLS > CHECK ELEMENTS > 3D > TET COLLAPSE , fix the error by tetra or manually by moving the nodes.
• Below image shows there is no tet collapse error.

• The above procedure same done at below shown part also.

MODEL 2 : 

• Import the given model and check the geometry error.

• In this model no need to perform the 2D mesh . Here we perform the 3D Quick tetra or Volume mesh.
• In option, 3D > TETRA MESH > VOLUME TETRA > SELECT THE SOLID.

• Before Mesh we can set the element size and Tet collapse value in Tetramesh parameter option.
• Below image shows the final result.

MODEL 3 : 

•  In model 3 not available in given attachment.

CONCLUSION : 

• Understand the types of 3D mesh used in different scenrio.
• The given model is meshed using 3D tetra elements.
