Week 8-3D Tetra Meshing Challenge
AIM:
To determine the given challenge.
OBJECTIVE:
To create a Tetramesh for housing component with following quality criteria.
PROCEDURE:
1.Import the model.
2.Select the import option on the tool bar menu and click on the imported geometry.
3.Click on the file sign then it will be shown the model then select it.
4.Click on the import button then it will be shown on the grpahic area.
5. After importing the model autocleanup the model before meshing the components.
6.After the autoclean up process take any one of the component from the model and start the 2D automesh for that component.
7.In 2D meshing select the elements as tria and set the element size as 5mm and select the surfaces that we want to mesh and click on the mesh button then it will be meshed.
8.After creating the mesh check the elements with the given quality criteria by clicking on the F10 shortcut button.
9.If the quality criteria is satisfied for the mesh then move on to the 3D mesh if not satisfies it then go on with the element cleanup.
10.After the quality criteria is satisfied move on the 3D mesh to perform the tetramesh operation on the same component.
11.To perform the tetramesh go to the 3D section in the main tool bar.
12.In 3D section go to the tetramesh option and open it. In that tetramesh click on the tetramesh parameters and give the max size, min size and tet collapse values as mentioned above.
13.After that values values have been assigned now go to tetramesh select the elements which we have to perform the 3D tetramesh operation on the component and click on the mesh button to apply it.
14.After the 3D mesh have been completed again check the quality criteria by clicking on the F10 shortcut button.If the quality criteria does not satisfied again try on remeshing the elements to get low tria failures.
15.After the completion of the 3D tetra meshing the components will be created.

2.Tetra Mesh Generation Method: Quick / Volume Tetra Mesh:
1.Import the model.
2.Select the import option on the tool bar menu and click on the imported geometry.
3.Click on the file sign then it will be shown the model then select it.
4.Click on the import button then it will be shown on the grpahic area.
5.After importing the CAD model just go on to the view option from the menu bar.
6.From the view option go to Browsers and select Hyperworks.
7.In that select the utitlity option to perform the quick tetramesh operation.
8.Then the utility bar is opened at the left side of the graphic area.
9.Then click on the Geom button from the utility bar.
10.After clicking on the Geom button another options will be displayed in that options select the Quick tetramesh from it.
11.On clicking the quick tetramesh option another window is displayed in that we have to give the component selection test colapse.
12.After giving all required quality criteria in the above table click on the mesh button. Then it will perform the quick tetramesh on the displayed component.
13.After the completion of the tetramesh check the elements wheather there are satisfied by the given quality cirteria or not.
14.If all the quality criteria can be satisfied then the component is obtained.
OUTPUT:
3.Tetra Mesh Generation Method: Quick / Volume Tetra Mesh:
1.Import the model.
2.Select the import option on the tool bar menu and click on the imported geometry.
3.Click on the file sign then it will be shown the model then select it.
4.Click on the import button then it will be shown on the grpahic area.
5.Take any one of the component from the model and start the 2D automesh for that component.
6.In 2D meshing select the elements as tria and set the element size and select the surfaces that we want to mesh and click on the mesh button.
7.After creating the mesh check the elements with the given quality criteria by clciking on the F10.
8.If the qualiity criteria is satisfied for the mesh then move on to the 3D mesh if not satisfies it then go on with element cleanup.
9.After the quality criteria is satisfied move on the 3D mesh to perform the tetramesh operatin on the same component.
10.To perform the tetramesh go to the 3D section in the main tool bar.
11.In 3D section go to the tetramesh option and open it. In that tetramesh click on the tetramesh parameters and give the max size, min size and tet collapse values as mentioned above.
12.After that values values have been assigned now go to tetramesh select the elements which we have to perform the 3D tetramesh operation on the component and click on the mesh button to apply it.
13.After the 3D mesh have been completed again check the quality criteria by clicking on the F10 shortcut button.If the quality criteria does not satisfied again try on remeshing the elements to get low tria failures.
14.After the completion of the 3D tetra meshing the components will be created.
