Bottle Cap challenge

OBJECTIVE: 1. To cleanup the geometry of the given component and to extract a mid surface for the same.

2. To assign thickness to the given mid surface.

SOFTWARE USED: ANSA 2019

PROCEDURE: The model that we recieved was a bottle cap model.

1. As we import a file in ANSA there are many errors that come with the geometry which we need to cleanup before going into midsurface.

We needed to fix the topology for the component. When the component was loaded the eroors were evident and thus we performed topology errors to the model.

After this we need to make some surfaces that were imported as unchecked faces in the model.

After the geometric cleanup the mid surface has to be performed.

As the geometry was very complicated manual meshing was performed in this process.

The model given to us also has a non-uniform thickmess so that is why we used weld spots to calculate the thickness of some components.

Now we make the mid surface using mainly two commands

1. Offset: This command was used with the selection of angle at 40 deg.

2. Middle: This command allows us to make a surface in the middle of 2 surfaces.

The middle surface was extracted from the model given.

The mesh of the mid surface is as shown

CONCLUTION: The Mid surface was extracted and the mesh was made with quality in hand.
