Project-2-Meshing of Door Inner Panel Challenge
Aim :- Mesh a Door Inner Panel with mentioned quality criteria.
OBJECTIVE:
- Extract the mid surface
- Geometry cleanup
- Meshing given door model using the given quality criteria checks
- Good mesh flow.
- Assign thickness
PROCEDURE :
- Import the component and click F to see the component in the GUI area as shown below.
As door model has thickness less then 6 mm we can use 2D meshing.
- Next step to generate Mid-surface
As shown in Snap model has many damaged surface, so auto mid-surface will not giving good surface
Result of auto mid surface :-
As automid not giving proper result we have to extract mid surface manually.
mid surface for main outer Panel :
Option used :-
Geom-surface edit-offset
i) Mask the outer surface
ii) Geom-surface edit-offset
Result :
- next step is to generate mid surface for circular surface as shown in snap :-
Defeature fillets for proper capture of geometry
Option used :-
Geom-defeature-surface fillets
result :-
For Generate mid surface option used :-
Geom-Surface edit-Offset
Result :
- Next step is to set extend circular surface upto main panel surface
Option used :-
Geom-surface edit-extend
Result :
- TO extract mid surface ribs as shown in snap i used diff. option as shown in snap beolw :-
Option used
Geo-Lines-Midline
Geom-surface edit-trims with lines
Geo-Surface-Ruled
- Next step is to extract mid surface for all ribs on model
Option used :-
Geo-Lines-Midline
Geom-surface edit-trims with lines
Geo-Surface-Ruled
- For all ribs mid surface same method is used
- Next geometry for mid surface as shown in snap(Slot)
Option used
Geom-surface edit-offset
Geom-surface edit-trims with line
Geom-surface-ruled
- Next geometry for mid surface as shown in snap(Slot)
Option used
Geom-Lines-mid line
To create surface between two line ruled option is used
for trim both surface , surface trim option is used
to extend upto base surface extend option is used
- All mid-surface are generated for all surface in model.
Complete Mid surface model with construction lines for better mesh flow :-
- Next step is to set Meshing criteria
Next step is Mesh the model surface by surface :-
Option used :-
2D-automesh
2D-Rebuilt mesh
2D- Quaility index
2D-edit element
2D-replace
Final Snap of Mesh model :-
- Next step is to check for edges inside mesh (No Open edges are found)
- Check for normals
Blue elements are need to align proper
- Next step is to assign thickness for all surface
- Comparsion of mesh model with CAD model
CONCLUSION:
The mid surface has been extracted for the given model and the mesh was generated within the given quality criteria.
