Week - 4 - 2D meshing for Plastic components
AIM:
For the given Plastic Bottle Cap model, check for the geometrical errors and take the mid surface by suitable mid surfacing techniques. PID and Thickness assignment has to be done for all the mid surfaces. Mesh the same with given element Quality criteria.

PROCEDURE:
1. The model which has to be meshed in imported in ansa application and the model is checked with the help of geometry checkup to detect any topology defect.
2. After doing the geometry cleanup we must measure the side of the component with the help of the measure tool in the tool bar.
3. After measuring the component we must offset the component by using the option called offset which is present in the tool bar.
4.We can take the midsurface of the plastic component, by using the offset option and select the component. Then we must choose the auto create option so that the element can be stored in a separate component.
5. After obtaining the midsurface, we can use the Cut option to hid and do topology to the component and remove the unwanted guide lines.
6.After proper geometric cleanup is done, we can start meshing the models separately which will help us to speed up the process in meshing and bring us a proper cleanup of the mesh flow and quality.
7. As the component is complex, we can cut the component and mesh the component so that mesh flow can be properly achieved.
8.The quality criteria is given as per the given data and the component is properly given to them.
9.From the above picture, we can see that the components are under the boundary conditions and with a proper flow of the mesh.
CONCLUSION:
For the given model, midsurface is taken and 2D meshing is generated in ANSA under the given quality critira with proper flow of the mesh.
