3D meshing using hypermesh

Objective :

To perform various types of 3D tetra meshing using hypermesh for the given components
by assigning given parameters

Procedure :

1. Import the given model and then split it to perform 3D meshing accordingly
   
   
   
   *Similarly with others models*
   
   
   
   
2. Take one component, which has to be meshed using 2D shell elements
   
   
3. To perform 3D tetramesh using 2D shell elements , the solids of the components has to be deleted using delete option
   
   
4. Then the surfaces are to be checked for mesh , to find irregularities
5. The irregularities are to be edited on the surfaces before 2D meshing using Quick Edit options and other options like Surface Edit
   
   
   
   
   
6. After the surface has been cleaned up manually , perform 2D meshing using 2D mesh option in the main menu bar
   
   
   
   
7. After 2D mesh check for quality of the mesh
   
   
8. After which perform 3D mesh - Tetra using tetramesh option in the mainmenu bar
   
   
9. In tetramesh dialog box select component option and Simple Pyramid to perform 3D tetramesh for the component
   
   
10. After 3Dmesh select few elements and mask them to view the meshed 3D elements
    
    
    
    
11. Similarly to 3D mesh other components using Volume tetramesh , import the model and split the component that is to be meshed
    
    
12. Select Solid or Surface option according to the present component status from the volume tetramesh options
    
    
13. Assign 2D type as Trias and 3D type as Tetras , assign element size
    
    
    
    
14. To change parameters , select tetramesh parameters in the tetramesh options
    
    
15. Choose Element size , Tetcollapse and assign values as required
16. Choose mask option to view the meshed component
    
    
    
    
17. Similarly to perform Quick Tetramesh import the model and split the component that has to be meshed
    
    
18. Select option View > Browser > Hypermesh > Utility
    
    
19. From the Utility tab select Geometry/Mesh option and the Quickmesh option to go to Quickmesh option window
    
    
20. Select component, element size , mesh type from the given options and then give mesh
    
    
21. Mesh will the completed by creating 2D shell elements over the component and then 3D tetra mesh
    
    
22. After creating 3D meshed elements , delete the 2D shell elements
    
    
23. After which check for Tetcollapse in the 3D check elements
    
    
    
    
    Check the Status bar for the number of failed elements
    
    
24. Edit the elements that are failed , using manual method
    
    
    
    
    
    
25. If the model that were mesh was a symmetrical model , then use Reflect option to minimize the meshing time by meshing one half and mirroring the other
    
    
    
    

Result and Conclusion :

Given models were 3D tetra meshed using different ways such as Quick mesh , Volume mesh and Tetramesh using 2D shell elements
