Meshing of Automotive Hood (CAR HOOD) - Sheet Metal Meshing
MESHING OF HOOD CHALLLENGE
Objective :
To perform geometry cleanup of Hood,extract midsurface and generate mesh following the given mesh criteria.
PROCEDURE:
- Enable By topo in visualization toolbar to visualize in topology display mode.And enable display fixed points in display toolbar.
- Extract the midsuraces of each component of geometry separately.
(Geometry>midsurface>extraction options>skin offset,select surfaces and extract midsurface).
- Perform the topology repair for each part separately.
- Latch midsurface
- Hinge Midsurface
- As the outer suface and inner surface are symmetrical the other half of the component can be deleted using delete option.So that to mesh only half of the component and reflect the same to the other side.
- Outer surface
- Inner surface
- Set the mesh criteria as per the given values (Preferences > criteria file setting > enter the given values and apply)
- Mesh the each component separately using automesh and use the clean up tools in qualityindex to rectify the failed mesh and maintain the flow of the elements.
- Latch surface
- Hinge surface
- Reflect the meshed half of the outer surface and inner surface using reflect tool.
- First duplicate the current elements of outer surface and reflect,(Tools>reflect>select elements,nodes and reflect)
- Duplicate the current elements of inner surface and reflect
Conclusion:
Midsurace of different parts of the hood are extracted separately using skinoffset tool
Meshing of latch surface, hinge surface,innersurface and outer surface of the hood are done as per the given mesh criteria using automesh & clean up tools in quality index.
