Week 11-3D Tetra Meshing Challenge

OBJECTIVE

• To create Tetramesh for the given models following each Quality Criteria.

PROCEDURE

(MODEL 1)

• Geometry was imported @IMPORT>FILES>IMPORT>GEOMETRY>ALL>IMPORT.
• Deleted the solids @DELETE>SOLIDS>SOLIDS>ALL/DISPLAYED>OK>DELETE ENTITY after getting a 'Topo' view.
• Remove fillets and minimum length areas @DEFEATURE>SURFACE FILLETS>SURFACES>FIND>REMOVE.
• Geometry cleanup was done @GEOMETRY>QUICK EDIT.
• 2D mesh was applied @2D>AUTOMESH>SURFACES>TRIAS>MESH.
• Quality was checked @TOOLS>CHECK ELEMENTS>2D>MINIMUM LENGTH.
• 3D mesh was applied to the component using @TETRAMESH>TETRAMESH>ELEMENTS>MESH.
• After applying mesh,component was 'Masked' and checked.
• Quality was checked @TOOLS>CHECK ELEMENTS>3D>TET.COLLAPSE.
• Failed was extracted using @TOOLS>CHECK ELEMENTS>MIN. LENGTH>SAVE FAILED>MASK>ELEMENTS>RETRIVE>MASK>REVERSE.

(MODEL 2)

• Geometry was imported @IMPORT>FILES>IMPORT>GEOMETRY>ALL>IMPORT.
• Deleted the solids @DELETE>SOLIDS>SOLIDS>ALL/DISPLAYED>OK>DELETE ENTITY after getting a 'Topo' view.
• Remove fillets and minimum length areas @DEFEATURE>SURFACE FILLETS>SURFACES>FIND>REMOVE.
• Geometry cleanup was done @GEOMETRY>QUICK EDIT.
• 3D mesh was applied to the component using @TETRAMESH>TETRAMESH>ELEMENTS>MESH.
• OR
• @VIEW>BROWSER>HYPERMESH>UTILITY>GEOM/MESH>QUICK TETRA MESH>COMPONENTS>PROCEED>MESH TYPE: TRIAS ONLY>MESH.
• After applying mesh, component was 'Masked' and checked.
• Quality was checked @TOOLS>CHECK ELEMENTS>3D>TET.COLLAPSE.
• Failed was extracted using @TOOLS>CHECK ELEMENTS>MIN. LENGTH>SAVE FAILED>MASK>ELEMENTS>RETRIVE>MASK>REVERSE.

(MODEL 3)

• Geometry was imported @IMPORT>FILES>IMPORT>GEOMETRY>ALL>IMPORT.
• Deleted the solids @DELETE>SOLIDS>SOLIDS>ALL/DISPLAYED>OK>DELETE ENTITY after getting a 'Topo' view for some components.
• 3D mesh was applied to the component (each seperately) using @TETRAMESH>VOLUME TETRA>ELEMENTS/SURFACE>2D:TRIAS 3D:TETRAS>MESH.
• After applying mesh, assemblies was 'Masked' and checked.
• Quality was checked @TOOLS>CHECK ELEMENTS>3D>TET.COLLAPSE.
• Failed was extracted using @TOOLS>CHECK ELEMENTS>MIN. LENGTH>SAVE FAILED>MASK>ELEMENTS>RETRIVE>MASK>REVERSE.

SCREENSHOTS

• @Sample 1 - After importing the file to Hypermesh.
• @Sample (2,5) - After geometry cleanup.
• @Sample (3,6) - After performing 2D mesh.
• @Sample (4,7) - After performing 3D mesh.
• @Sample 8 - Final model both after 'Quality Check'.
• @Sample 9 - Geometry cleanup done after importing.
• @Sample 10 - 3D meshing done.
• @Sample 11 - Masked view.
• @Sample 12 - Failed trias view.
• @Sample 13 - Final model before exporting.
• @Sample 14 - Importing the assembly.
• @Sample (15,16,17,18) - Volume 3D mesh done for each.
• @Sample 19 - Final model before exporting.
