Week - 4 - 2D meshing for Plastic components

AIM

To check the geometrical errors and take midsurface of the model, and do the meshing on the midsurface with the given quality parameters and assign thickness to the mid surface

PROCEDURE

1. Open the model in ANSA
2. Peform Cons resolution
3. Orient the surfaces
4. Check the geometrical errors
5. Measure the thickness and store
6. Extract the mid surface

For Lower and Middlle rings - used OFFSET option

For Fins - used MIDDLE option

For ribs - Used MIDDLE MULTI , performed extend option to extend the faces to the surface and intersected ,rotated the midsurface by performing ROTATE usibg COG points

For teeth -Created MIDDLE curves , projected the curve to face and generated new face by coons, performed extend option to extend the faces to the surface and intersected ,rotated the midsurface by performing ROTATE usibg COG points

For Top face- used OFFSET by FEATURE selection tool

1. Add target length elements in mesh module
2. Assign proper mesh parameters and quality criteria
3. Generate the mesh
4. Used BEST,RECONSTRUCT.SPLIT.IMPROVE.SMOOTH options for better mesh flow
5. Assign thickness to the model
6. Release the FE model
