Week 5 Challenge : Surface wrap on Automotive Assembly

AIM:

• To mesh the given models,

1. Check for geometrical errors,
2. Delete unnecessary surfaces for the surface wrap,
3. And merge all the 3 models to perform surface wrap.

PROCEDURE:

ENGINE:

• Import geometry from file->open->file location->challenge5 Engine.ansa.
• Initially always the geometry will be in wireframe mode.
• Click on SHADOW mode and enable labels to show the tool names.

• Shadow mode:

• Change ENT to PID mode.

GEOMETRY CLEANUP:

• Delete unnecessary parts which are present in the engine.

• In we are going to clear the unwanted parts except for engine parts.
• In this picture if we observe the balls and rings are overlapping the surfaces.
• So, delete it directly.

• From this highlighted ring we can clearly say this is not an engine part.
• Delete the parts which are present like this.

• Here there are so many unwanted parts that are present, so use NOT and PID to hide engine parts.

• I hid the main engine parts and these are the remainings.
• Use universal delete and delete unwanted parts.
• But before deleting, make sure it is unnecessary or not.

• We can directly delete these rings.

• These are the remaining parts after deleting,

• Now do all and check for other errors,
• We can delete the above surfaces also.

• Delete these coons using TOPO->CURVES->DELETE.

• From now we can check one by one part and clear red and blue coons.
• Here it is showing red coon,

• First hide the outer surface and see what is happening inside.
• The ring is getting selected, so delete the ring and do topo.

• It's done here, do the same for others too.

• Delete this surface.

• Do TOPO.

• Do the same procedure for all and show the before and after images.
• Before,

• After,

• Hide the upper surface and delete the inner extra surface.

• It's done.

• We can delete the bells directly.

• Now clear these blue coons as we did before.

• Hide the upper surface and clear these blue coons.

• Blue coons are cleared.

• Now focus on these parts and clear the errors.

• Isolate the surface and delete the inner surface.

• Do all, it's done.

• Close the opens if it is completed.

• Close the red coon surfaces.

• Follow the same procedure here also,

• All done here.

• We don't need these belts. So delete it directly.

• We have cleared all the errors on this side.

• This side also we have done the geometry cleanup.

• Close the opens if it is completed.

• Close the red coon surfaces.

• Follow the same procedure here also,

• All done here.

• We don't need these belts. So delete it directly.

• We have cleared all the errors on this site.

• This side also we have done the geometry cleanup.

• This side is also done and closed 3 sides of the holes.

• These are the last errors that need to be cleared.

• All the errors have been cleared and opens have been closed for the surface meshing.
• Save the engine part and start the next.
• Final View:

TRANSMISSION CLEANUP:

• File->open->file location->transmission.ansa.
• In the beginning it is showing in the wireframe mode.

• Add shadow mode and enable labels.

• Now change ENT to PID mode.

GEOMETRY CLEANUP:

• Do the same procedure to clear the errors.
• Delete the inside ring.

• Now it is changed to yellow coon.

• Hide the surface and delete the unwanted surface.

• There is a surface that is making triple coon.

• Hide the surface and delete it.

• Hide the surface and delete the unnecessary surface over there and do the same for others.

• All the blue coons are cleared.

• Final View:

GEAR-BOX CLEANUP:

• Initial geometry with wireframe mode.

• Enable shadow and labels.

• Change it to PID mode.

• In this part these are the only visible blue coons and errors.

• Follow the same steps as we did before.
• Use I-NOT and isolate the tool and clear the errors.

• It's done.

MERGE ALL THE 3 PARTS:

• Now open the engine and go to FILES->CLICK MERGE.

• It will ask which part needs to be merged,

• After the selection of the part, one popup box will come.
• In that always choose to merge with the current model and on the auto fit models to automatically connect->ok.

• There are no errors it is showing, which means it is merged properly with the current model.

• Next merge the gear-box.
• Here also no errors are showing, so it is also merged properly.

• Now close the holes which are still not closed.

FINAL FULL MODEL BEFORE MESHING:

WRAP MESHING:

• Go to classic mesh -> under ELEMENT also WRAP is there/ OCTREE also WRAP is there-> we can choose anything.

• After clicking on the WRAP the status is empty,
• Click on the empty,

• Now click on untitled,

• Give name and target length, The name I gave is WRAP, and the LENGTH is 5mm.

• We can change this MESH parameter also and give OK.

• Previously the parameter was untitled, now it is changed to WRAP.
• The content is 0 initially,

• Click on the content -> select the PIDs ->Click on the green forward error.

• PIDs moved to anthe another side.

• Now the content and parameter have been assigned.

• Click on the RUN button and wait for the model to wrap the mesh of the model.
