Project 1-Meshing of Rear Wheel Holder challenge

Aim :- Meshing of Rear Wheel Holder 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 model has some geometry problems we need to fix that :-

Options used to fix snap problems :-

• Geom-Quick edit-split surf line
• Geom-Quick edit-split node
• Geom-Quick edit-toggle edge
• Geom-Quick edit-delete surf
• Geom-Quick edit-filler surf

As door model has thickness less then 6 mm we can use 2D meshing.

• Next step to generate Mid-surface

Options used to get good surface :-

• Geom-Quick edit-split surf line
• Geom-Quick edit-split node
• Geom-Quick edit-toggle edge
• Geom-Quick edit-delete surf
• Geom-Quick edit-filler surf

Result of auto mid surface :-

• For better mesh flow we have to do some geometriacal clean-up

• Geom-Quick edit-split surf line
• Geom-Quick edit-split node
• Geom-Quick edit-toggle edge
• Geom-Quick edit-delete surf
• Geom-Quick edit-filler surf

• As the mid-surface is generated now next setp is mesh the model surface by surface
• Before meshing the qiality criteria requirements can be filled by the command: preferences + criteria file settings

Option used for meshing :-

• 2D- automesh -surf
• 2D - rebuilt
• 2D - qualityindex - all options
• 2D - edit element
• Geom - node edit

Some Meshing Snap :-

• Next step is to check for edges inside mesh (No Open edges are found)

• Check for normals 

• Next step is to assign thickness for all surface

CONCLUSION:

The mid surface has been extracted for the given model and the mesh was generated within the given quality criteria.
