Assignment 1-2D Meshing Challenge
2D MESHING
OBJECTIVE: To clean up geometry and create midsurface of models and then do 2D meshing of the models.
MODELS:-
The models are imported in hypermesh using option of import model in tab bar.
PRACTICE
CLIP REPAIR
MOUNTING BRACKET
CRITERIA:-
Target Element Size= 5mm.
Minimum Length = 3.5 mm
Maximum Length = 7 mm
PROCEDURE:-
Practice
- First the model is imported using import model option in tab bar in Hypermesh and the required component is separated out and the solid part is deleted.
- The model has surface fillets are removed using surface fillets option (Geom>Surface edit>Surface fillets) and pinholes of diameter less then 5 mm using pinholes option (Geom>Pinholes).
- Now we have to geometric clean up of the model using quick edits (Geom>quick edits)
- Now we to create midsurface of the model using midsurface option (Geom>midsurface)
- Now we put the criteria given (Preferences>Criteria file editor)
- The meshing of the model with target element= 5 mm is done (2D>automesh).
- Now we have to create a new property for the mesh with thickness in property equal to model thickness.
- Assign the new property to the mesh.
- Plot the mesh metric using quality criteria option (2D>Quality Criteria).
