Week 5 Challenge : Surface wrap on Automotive Assembly

Aim

To do surface wrap over assembled parts such as engine,transmission and gear box

Target length for Wrap = 3mm

STEPS

• Unwanted surface are deleted without damaging the outer shape of the geometries.
• Single cons are resolved mainly here as it would affect negetively on the surface wrapping.
• After cleaning up the geometry from the unwanted surfaces it is then solved.
• Then whole three geometries are merged together to form the required system.
• Surface wrapping tool with constant length of 3mm is chosen from the meshing interface.
• It is then named and the required parts are selected(all) and the run button is pressed to start the surface wrapping.

Models

1. Engine 

2. Gear box 

3. Transmission :

• Go to Classic Mesh --> Element ---> Wrap ---> Constant Length.
• Double click on 'Constant wrap Octree'.

• Double click on 'parameters'.

• Castellation - Give target length 3mm

• Enable Nodes out of structures.
• Enable Assign properties from structure.

• Provide Any name like 'Full-Wrap' and click on 'OK'

• Now i cancel this pop-up window and Click on properties and we can see the properties and delete the PID's of deleted surfaces.

• so in order to see how many PID, go to Compress tool which can be seen right upper of the pop-up window.
• To Delete the PID's go to compress tool and click on OK and all the unnecessary PID's delete.

• Click on green button to perform operation and click on OK.

•  The one pop-up window will open and hit on RUN button.

• Then the below model is coming out. 

RESULTS

Conclusion 

• Surface wrapping was run successfully on the given parts.
•  Surface wrap is effective for outside flow simulations where the volume between the body and wind tunnel is required for flow over the body simulations.
• Effective surface wrap is achieved on the given body for a given mesh length of 3mm.
