Assignment 1

Aim:

The main aim is to perform the geometry clean up and to give a mesh to the given sheet metal component, Clip Repair model, and Mounting Bracket Model.

Methodology:

The methodology to get the mesh effectively.

1. Opening the file
2. Extracting the Mid Surface.
3. Giving the mesh
4. Clearing the Errors
5. Giving the material Property

Procedure:

1. Opening the file:

• The File opening does requires few steps to be followed which then results in the opening of the file.
• When the app is opened, the file asks us which user interface to open. Select “RADIOSS”
• To open the file, Go to the File, on the main menu >>Open >> Click
• If the File is didn’t appear click on the display panel and enter Keyword “F” and the component will be displayed.

2. Clearing the Geometric Errors:

• The geometric clean up can be done by using the tools in the quick edit panel.
• The model didn’t have many errors, the free edges were cleared by using the Toggle tool and Fillet surface tool.
• Go to the Geom tab, Quick edit Panel, where you can find the tools required to perform the clean-up.

3. Extracting the mid Surface:

The mid surface for this part is done in 2 different ways the auto and manual mid-surfacing. The Auto Mid surface is done normally for all the surfaces. The Surface given can be done with the auto mid surface extraction option.
Auto Mid Surfacing:

• The Auto Mid Surface is done for the Inner Sheet metal part of the rear door of the car component.
• Go to the Geom Panel, Select mid surface >> Select Extraction options >> select Skin Offset instead of Offset + Planes + sweeps. >> Go to the Auto Extraction >> Select the Surface >> Click Extract.

4. Giving the Quality Criteria:

• Quality Criteria for this model are given.
• In status bar, Preferences >> Click Criteria File Setting >> Give the criteria >> Click Apply >> Click OK

5. Giving the Mesh:

• The mesh is to be created on the mid surface so that the main part doesn’t get affected.
• To mesh the component, Go to 2D Tab, Select Auto meshing >> select surfs >> give Element size >> Select Mesh Type as mixed >> Click Mesh.
• To reconfigure the mesh select quality index in the 2D tab, Select Cleanup tools >> The Tools are used to modify the mesh to get the proper mesh.
• Click F7 to align the nodes. Select the nodes of 1^stend and 2^nd end and then select the nodes.
• To Project the meshed lines to the Feature line, the Project tool is used. Go to the Tools Tab >> Select Project >> Select To line >> Select the nodes >> Select the lines >> Click Project.

6. Clearing the Errors:

• To clear the Errors, the Quality Index Panel is used. The Quality index panel consists of a different set of tools to make an error-free mesh.
• Go to the 2D Tab, Click Quality Index >>Select Clean up Tools.
• Use the tools to create an optimum mesh.

7. Giving the material Property:

• The Material properties are to be given to the component.
• To Create a Material card, Go to the Model Browser, Right Click >> Click on the Create >> Material >> Give a Name to the Material.
• To Create a Property card, Go to the Model browser and right-click on it >> Click on Create >> Select Property >> Give a name to the property>> Give the Thickness of the Model>> Give the Material to the Property.
• To assign the Property to the component, Go to the Model Browser, Select the Component >> Right-click on it, Click Assign >> Select the Property to assign.

Result:

The Given Models are clean-up, meshed and the thickness is added to the model.

Thickness added to the Component:
