Assignment 1-2D Meshing Challenge

OBJECTIVE

• To carry out cleanup operation procedure on the given files without any free edges, converting all of them into refine geometry.

PROCEDURE

• Geometry was imported @IMPORT>FILES>IMPORT>GEOMETRY>ALL>IMPORT.
• Deleted the solids @DELETE>SOLIDS>SOLIDS>ALL/DISPLAYED>OK>DELETE ENTITY.
• Fillets present at the feature areas were removed using @GEOMETRY>DEFEATURE>SURFACE>FILLETS.
• Necessary model cleanup was performed within the geometry itself.
• Midsurface was extracted using @GEOMETRY>MIDSURFACE>AUTOMIDSURFACE>EXTRACT and also used @GEOMETRY>MIDSURFACE>FINAL EDIT TOOLS for difficult capturing areas.
• Other failed feature areas were manually extracted using the @GEOMETRY>SURFACE EDIT>OFFSET.
• Necessary topology cleanup was done using @GEOMETRY>QUICKEDIT and SURFACE EDIT (for extending by duplication).
• Meshing was done at each phase by considering the given 'Quality Criterias' and deployed using @2D>AUTOMESH>MESH.
• Needed cleanup was done upon the model using @2D>QUALITY INDEX>CLEANUP TOOLS.
• Edges were checked at @TOOLS>EDGES>FIND EDGES and 'Normals' were also verified.
• Cleanup tools were used at quality index for modification of elements @2D>QUALITY INDEX>CLEANUP TOOLS.
• Material and Properties were also assigned to model at different 'Thickness' areas @MODEL Panel>CREATE>PROPERTIES/MATERIALS, assigned thickness considering the Parent Geometry and '2D Detail Element Representation' was also done.
• All the procedures done were verified by switching to '1D Detail Element Representation'
• Then, geometry was 'Exported' @FILE>EXPORT>choose file>rename as needed>EXPORT.
• All the needed screenshots have been attached along with final model image.
• And as instruced 'Important Points to Remember' were also followed.

SCREENSHOTS

• @Sample (1, 2, 3) - Importing the models.
• @Sample (4, 5, 6) - After doing necessary cleanups.
• @Sample (7, 8, 9) - Extracted midsurface.
• @Sample (10, 11, 12) - Meshing the models.
• @Sample (13, 14, 15) - Edges were checked and normals were verified.
• @Sample (16, 17, 18) - Thickness assigned were checked.

RESULTS

• Geometry cleanup was done, midsurface was extracted and 2D meshing was also done. Property and thickness was assigned to the meshed model and checked.

CONCLUSION

• Target element length (max.) was failed at some regions.
