Week 12:Project 2-Meshing of Rear Wheel Holder challenge

Meshing of Rear wheel holder challenge:

Objective:

To mesh the rear wheel holder with the mentioned quality criteria and assigning them the thickness.

CAD Model Image:

Procedure:

• Firstly import the model from the system files.
• Before extracting the mid surface remove the buttons as shown in the figure.
• Then auto extract the midsurface as the offset value is same for the whole component.
• For auto midsurface Goto>Geom>Mid surface>Auto mid surface.
• After completion of mid surface clean up the geometry by using geom tab with quick edit option.
• Delete the surface wherever needed and create a surface for that for attaining a good surface.
• Use 'Toggle edge',Filler surface option to create a perfect surface for meshing.
• Before meshng assign the meshing parameters and quality criteria.
• For assigning Goto>Preferences>Criteria file settings.
• In criteria file settings assign the values as mentioned and click apply.
• Then after perform meshing Goto>2D>Automesh>Mesh.
• Assign the element size as 5mm and perform meshing.
• Select the mesh type as mixed.
• After meshing check the mesh flow and confirm the mesh.

• After mesh is confirmed check for elemental failure in the model Goto>Tools>Check elements.
• To get rid of elemental failures Goto>2D>Quality Index panel.
• In quality index panel use the options use element optimization,place node and combine tria elements to get rid of failure elements.
• Make sure that tria concentration is very less to get rid tria use an option called Drag tria elements for opposite trias to form quad elements.
• Check for proper mesh flow of the component.

• And after meshing create individual components for all of them according to thickness.
• And also create a individual property for the components .
• Assign the thickness to the property and after that assign property for each individual components.
• Assign the individual components with colour for easy recognization.

Result:

The given rear wheel holder is meshed accordingly as per mentioned quality criteria by performing mid surface and assigning the thickness to the components.
