Week - 4 - 2D meshing for Plastic components
Aim : To make geometry clean-up and midsurfacing of given model followed by meshing with proper quality criteria.
Procedure :
- After downloading the file it converted into ansa file and open in ANSA software.
- First step after downloading model is to check quality criteria that whether it fails to quality criteria or not, if it fails then fix all the errors like (tripple cons,niddle edge,unchecked faces etc.)
- After fixing all the errors re-run the check manager.
- After geometry clean-up go to mid-surfacing process. In midsurfacing we can use offset method, face-middle method, curve-middle method.
- As given geometry is complex geometry so we have to divide that geometry and midsurface different parts seperately.
- We have to midsurface teeth and threads seperately by using following steps:
- 1) We have to use first curve middle option for teeth. 2) After that project that curve to base surface. 3) Lastly use new option to create surface between that curves.
- After completing all the midsurfacing of whole model we have to assign PID to midsurface with thickness of 1mm.
- After midsurfacing we directly go for meshing, before meshing we have to assign quality criteria.
- when we see the model in hidden option we can see whether our model fail in given quality criteria or not.
- If it fails then we have to go for reconstruction, split and swap option as per requirement. Also we have to remove trias at edges also immediate trias, rotating trias in given geometry.

Learning outcome:
- In this challenge I learnt about how to make geometry clean-up and midsurface of complex parts.
- Also how to midsurface teeth and threads seperately by using curve - middle option.
- How to mesh complex parts within given quality criteria with proper mesh flow.
Conclusion:
In this way I completed geometry check, midsurfacing and meshing within quality criteria with proper mesh flow.
