Performing the cleanup and meshing the geometries by using the Hypermesh software

Object: In this challenge, we are performing the cleanup and meshing the geometries.

The below procedure we are following to clean up geometry and meshing the geometries.

1. Clean the geometry.

2. Extract mid surface.

3. Cleaning the mid surface geometry.

4. Creating the 2D mesh on the mid surface.

5. Assign thickness to the 2D mesh.

  1. Clean the geometry.

 The process starts with importing the geometry with the help of an import solver disk. After importing the geometry we move to work on the geometry cleanup. In this, we fill the gap between the surfaces, toggle the lines by using the toggle option from the quick edit tool and close the small surfaces by using the filler surface option from the quick edit tool. 

The above figure shows the importing the geometry.

2. Extract mid surface.

The extracting the mid surface from the geometry is important to increase the speed of the analysis and easily modify the mesh.

 The extracting the mid surface from the geometry is two methods. one is auto-extract by using the mid surface tool from the Geom and another is a manual mid surface by using tool offset from the surface edit.  

The above figure shows the extracted mid surface from the geometry.

3. Cleaning the mid surface geometry.

The cleaning the mid surface geometry is similar to cleaning the main geometry. In this case, we are using similar tools for cleaning the mid surface geometry. The tools we are using are the Quick edit tool, surface edit tool, etc.

4. Creating the 2D mesh on the mid surface.

   Creating the 2D mesh on the mid surface we are following these parameters target length 5mm, min 3.5mm, max 7mm.

The mesh can create on the mid surface by using the auto mesh tool from the 2D panel. Creating the mesh is nothing but creating the elements with the help of nodes. later the analysis is carried out on this mesh.

The above figure shows the meshed mid surface geometry. 

  After meshing the geometry we move to check the quality of the mesh by using the quality index tool from the 2D mesh and checks element from the tool. By using these tools we minimize errors like minimum length, maximum length, Jacobin and aspect ratio, etc. 

5. Assign thickness to the 2D mesh.

After creating 2D mesh on the mid surface geometry we assigning thickness to the mesh by using the property tool. After assigning the thickness to the 2D mesh that mesh turns into the 3D mesh.

Conclusion:

1. We learn how to clean up the geometry and extract the mid surface from the geometry.

2. We learn how to create the mesh on the geometry and assign the thickness to the geometry.

3. We learn the new tool ruled. Using this tool we are creating the mesh on the geometry.
