Week 5 Challenge : Surface wrap on Automotive Assembly

AIM:

• To perform surface wrap on the given automotive assembly.

OBJECTIVE:

• To perform geometrical cleanup of given assemblies separately
• To merge all the components and to perform surface wrap of the same.

PROCEDURE:

• Open the geometry in the ANSA software. Clean up the surface of geometry by deleting unwanted parts and faces present on the geometry. As surface wrapping is generally carried out to study the flow over a surface So the main importance should be outside surface rather inside parts and surface.
• Close all the holes present in the geometry otherwise while wrapping it might create disturbances. The below diagram shows the final geometry before assembly. Repeat the above step 1 and 2 for all the geometries.

Cleaned Up Model:

• After the clean-up, the open holes are filled for the perfect surface wrapping.

• From the file, section select Merge and select other geometric files and click ok. Thus it creates an assembly of different parts. The below figure shows the merged assembly.
• Now move to the mesh session and select the Wrap option from the element dropdown. In wrapping select constant length as in this it is a constant length surface wrapping.
• Provide target length and smooth factor as 2 and 0.5 respectively. Smaller target length help to create more accurate wrapping though it might take time. Then provide contents by selecting all the PIDs and clicking ok. The final surface-wrapped model is shown in the Result and Discussion session.

RESULT AND DISCUSSION:

• Surface wrapping is generally carried out to study the flow over a surface so, the main focus should be outside surface rather inside parts and surface. The below figure shows the surface meshed model of the given automotive assembly.
• After surface meshing to check whether the wrap obtained is correct, it is advised to check the inside of the wrapped surface. If it creates a pure hollow inside (as shown in the below figure) thus proper surface wrapping is obtained.

CONCLUSION:

• A study carried out on surface wrapping and surface wrapping of a given automotive assembly has been completed.
