Meshing of bottle cap using ANSA

Aim: To create a meshing of bottle cap check for the geometrical errors and mesh the mid surface with given element Quality criteria. After meshing the component the thickness has to be assigned.

Procedure:

1. Open the model in Ansa before assigning the quality check for geometry issues and fix them.

2. After the geometry check extract mid surface for each part in the bottle cap. In this model, there are no different parts attached so I have manually separated the top and bottom with different PID.

3. Now it is easy take mid surface becaause the top and bottom parts is visibe and can create mid surface for small ribs and threads.

i have used faces middle for ribs on the bottle and offset for rest of the surface, in fillet area i have measured the distance of inner and outer fillet area and used faces offset.

In thread area i have used curves middle and extenden it to the mid surface, i did refer the article given.

4. Now after creating the midsurface from the parent body i have assigned th eproperty and joined it together.

5. Now assign the quality criteria and in mesh mode enable Hidden drawing style so that the quality issues will be visible.

6. Now after completing the mesh we have to assign thickness for the mid surface. Thickness is measured with the parent body part and added to the mid surfaced part.

Result:

Few images below show the complete mesh model of bottle cap as per the quality criteria and also the thickness has been assigned.
