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.

Quality Criteria

Procedure-

1.import model to ansa workspace.

2.Do geometry clean up.

3.Resolve model isues if observed either by auto fix or mannually.

This model having some minnor issue which can be autofixed.

4.Next step is mid surface generation.

Before going for midsurface generation need to measure the thickness of component. AS it is plastic component it is having different thickness at different parts.

midsurfacing is done using commonds like faces-offset,faces-middle and curve middle after using curve middle from generated curves we need to create new surface using faes-new command

New pid are set for each midsurface.

5.After midsurfacing next is to define quality criteria and mesh parameters.

6. After defining quality criteria next part is meshing of componet using best mesh command.

After checking need to check and resolve the quality issues as per quality criteria.

Learnings-

Manual meshing of plastic component having varrinng thickness.

Resolving the quality issues generated in meshing.
