Week 5 Challenge : Surface wrap on Automotive Assembly
Aim:
To 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.
Objective:
we have to take a target length given below
Target length for Wrap = 3 mm
step 1:
First we have to 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.
Next, we have to delete the unnecessary surfaces in the exterior using the Delete option. We can observe the rings which have no significance. The designer might have used rings to create fillets in the model.
We have to delete unwanted rings and surface by using universal delete option
Gear box topo clean-up:
After completed topo clean-up the gear box image will look like this
Transmission geometry:
we have to clear the single cons and triple cons errors by using
After geometric clean-up, merge the different models into one model. Click on the File and click on the Merge option. Select the model file that is to be merged
Surface Wrap:
For the Surface Wrap, after the geometrical clean-up, click on the Wrap option in the Element module in the Mesh deck. Option for the Constant Length option.
We have to give the target length 3mm
Next step we have to double-click on the 0 (Content) for the selection of PIDs to mesh under the Constant Wrap Octree. Select all the PIDs and click on the Move option (green arrow) to move the PIDs into the Octree Scenario List. Click on Ok.
After assigned the PID we have to check the volumes
Finally, this means the surface wrap is done successfully
Conclusion:
Finally, thus the Surface wrap along with eliminating geometrical errors and topo clean-up has been generated successfully. For it to get the finer surface wrap we need to reduce the mesh size which even takes lot time to generate the surface mesh and consumes time but generates a good geometrical mesh.
