Week 5 Challenge : Surface wrap on Automotive Assembly
Aim :
For the given models, check for the geometrical errors and delete surfaces which are unwanted for Surface wrap as shown in the videos. After clearing geometry, Merge all 3 models and perform surface wrap.
Target length for Wrap = 3 mm
Procedure :
- First the model is loaded on to ANSA
- 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.
Model :
1. Engine :
2. Gear box :
3. Transmission :
- Go to Classic Mesh --> Element ---> Wrap ---> Constant Length.
- Double click on 'Constant wrap Octree'.
RESULTS :
earning Outcomes
Geometry cleanup
Geometry merging
Surface wrapping
Conclusion
1. Surface wrapping was run successfully on the given parts.
2. 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.
3. Surface is easier to perform since it does not depend on the quality of the wrap on each material as we are not interested in physics in the body.
4. Effective surface wrap is achieved on the given body for a given mesh length of 3mm.
