Week - 4 - 2D meshing for Plastic components

• The bottle cap is imported to ANSA then check for the geometry errors.
• The geometry cleanup is done using auto fix.
• After the geometry clean up is done, i have tried to get the auto midsurface from ANSA, proper faces are not generating, So i have used the manual mid surface.
• After the mid surface extraction the average length is given as 1 for all the perimeters. Using the Best option the meshing is done, For alterations in meshing I have used the Smooth, reconstruct, split, and increasing or decreasing the perimeter nodes options. I have tried to minimize the OFF elements as minimum as possible, but i could not able to avoid it.
• After meshing is done the draw shell as solid option is enabled and is shown in the figure.

LEARNING OUTCOMES:

• I have learned the procedure to mesh the plastic component using ANSA.
• I have explored different options like Auto mid surface extraction, different difficulties while extracting manual mid in ANSA while doing this challenge.
• I have learned how to deal with the meshing difficulties arises during meshing.
• I have learned how to deal symmetry options and rotating option during this challenge.

CONCLUSIONS:

In this challenge the importing the geometry, geometry cleanup, assigning the thickness to the model, auto mid-surface extraction,manual mid-surface extraction and meshing is performed with minimum OFF elements . The application of loading and boundary conditions are performed for upcoming challenges.
