Week 6-Meshing of Hood Challenge

CHALLENGE 6: MESHING OF HOOD

AIM:

For the given Hoodel model, extract the mid-surface and generate its mesh maintaining the required quality criteria.

CAD MODEL:

PROCEDURE:

• Open the model and view in By Topo mode. Check the surfaces for geometric errors or edge connectivity .

• Use Quick Edit panel to toggle the edges if required.
• Extract the mid-surface of the model using Auto-midsurface panel.

• Remove or delete the symmetric half of the mid-surface.

• Apply Autocleanup panel to clear any geomerical or surface edge errors. Set the required parameters in autocleanup settings.

• Holes, fillets and construction lines are cleaned by the software. Further requirements has to be done manually.
• Create washer splits around holes for better mesh pattern.

• Toggle/suppress the construction lines wherever required.

• Input the required values in the Criteria settings.

• Set the mesh parameters in the Mesh settings.

• Mesh the entire surfaces maintaining the quality criteria and mesh flow.

• Mask the elements which does not need to be replicated to the other side.

• Select the vectors to define a plane of symmetry and reflect the elements.

• Unmask all other elements to obtain the full mesh of the model.

• Preview equivalence and apply to join the free edges of reflected portion.

Final Model:

RESULT:

The given Hood model has been meshed by generating mid-surface and the quality criteria are satisfied.
