Week 6-3D Tetra Meshing Challenge

FOR MODEL 1

1 - First step to start the challenge we download the model from the question.

As step or igs file. After this we import the model in hypermesh. Import> geomerty>import. Then press F in the keyboard for fitting the model on working screen.

2 - In this we go for the topology cleanup work if any hole, cracks are present and any feature line are not present or not required we toggle the the line . Go to menu bar> geometry>quick edit panel.

3 - After this we can create a 2d mesh on the surface by automesh option in this option put the element size and select only tria for mesh for meshing by main menu bar>2D>automesh>select surface or press f12 in the keyboard.

3 - Before that we will set the quality criteria, parameter and topology revision.

4 - After this we correct the quality failure if any persent in mesh and also we check flow of the mesh.

5 - Then we check the feature capturing of the mesh, meaning mesh is capture the model or surface correct or not.

6 - Then we go for the final checks like find edge, check connectivity, duplicate.

7- After this we can go to create this 2d mesh into 3d tetra mesh by 3d> tetra> tetra mesh> select the 2d element> put your tet collapse quality criteria> mesh or create.

MODEL 2 -

PROCEDURE

1 - 1 - First step to start the challenge we download the model from the question.

As step or igs file. After this we import the model in hypermesh. Import> geomerty>import. Then press F in the keyboard for fitting the model on working screen.

2- then we go for directly to volume tetra mesh>select the solid and put the element size >.select the tria type> elements in current component>go for mesh.

3- At this time u see the volume mesh on the solids. Last step we check if any quality failure is present in model or not for this we go to tool>check element>3d option select >tet collapse. Or we direct go by press F10 in keyboard.

MODEL 3 -

PROCEDURE

1- In this model same procedure before the steps of creating quick tetra so when we create quick tetra mesh we can goto the view >browser>hypermesh>utility>geo/ mesh option>quicktetra>then select the component and the element size>element type >mesh the component.

2- After completing the mesh we found the 3d mesh help of quick tetra method.

Above image before create the quick tetra mesh

Above image after create the quick tetra mesh

3- Last step we check if any quality failure is present in model or not for this we go to tool>check element>3d option select >tet collapse. Or we direct go by press F10 in keyboard.

LEARING OBJECT -

In this challenge we use and learn this tools and options.

a. Create 2d elements into a 3d mesh by tetra mesh option.

b. Edit element option for create element, split the element, combine the two tria element and for this option we use a shortcut key F6.

c. Replace option for use the nodes replace option and use shortcut key F3.

d. Organise option for move one part to another component and use shortcut key shift+ F11.

e. Use rebuild option for reconstruct the element.

f. For generate the mesh we use automesh by use shortcut key F12.

g. Quick edit for the geometry cleanup use shortcutkey F11.

h. Use the reflect option for copy the symmetry part .

i. Use mask option for hide the part use shortcut key F5.

j. Here we also know about the final checks after meshing like connectivity, normals, edges, duplicate element.
