Week 12:Project-1-Meshing of Door Inner Panel Challenge

OBJECTIVE:

To mesh the model with element size of 4mm and follow the Quality Criteria and assign thickness for the given model.

PROCEDURE:

The side door model file is imported to hypermesh using import option.

Delete the solids in the model if any solid is available.

Geometry clean up is done as there are a lot of fillets which is removed using the defeature > surf fillet option and using the quick edit option toggle close lines and check for free edges that are unwanted.The geometry cleanup is done using various options available in quick edit and edge edit and is checked for missing surfaces.

After geometry clean up is done midsurface is extracted separately for each surface. Some surfaces are failed to generate the midsurface using the automidsurface option in that case the offset option is choosed to create the midsurface.

For the ribs the midline is created between the lines and the lines are projected to the surface and then using the ruled option from the surface surface is created.

Replace point and delete surface is used to delete unwanted surface

The midsurface components are separated to different collectors and is organized using Tool-> organize .

Using the 2D-automesh option each part is meshed separately and the meshflow is checked individual parts for proper mesh flow.

After the components are meshed they are checked using quality index option and using element optimize, combine , drag tria they are fixed.

For assigning the thickness we first as to be create the property of required thickness and assigning the property according to the thickness of the surfaces.Create properties to generated ribs and other features with respectives thickness and assign them to component collectors.material is created as steel and it is assigned to all the property .

the properties are assigned to the components based on their thickness.

CONCLUSION:

The Geometry is cleaned and the midsurface is extracted for the components and is organized based on thickness and is meshed for proper mesh flow and clear quality criteria and assign thickness for the components.
