Challenge

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

Aim :- mesh the Side Door component and assign thickness , Follow the Quality Criteria

Target Element Length = 4 Units

Procedure :-

Import the given .hm file into hypermesh , go to - import model- select file- import.

It is difficult to generate midsurface for the given single complex component , so split this into 4 components.
Put in BY COMPONENT view mode to see components with assigned colours.
For this type of components auto midsurface may not give proper midsurface ,so generate midsurface manually using OFFSET option.
before offsettng the surface defeature the ribs , go to - geomtry- defature-surf fillets
go to - geometry -surface edit- offset , Taken styling surface (outer surface ) for reference
Component like shown below , features are overlapping so project one feature onto another and represent both features on single surface
After generating midsurface do geometry cleanup using defeature , surface edit ,quick edit options.
on engineering surface(inner surface) ribs, snaps and some other features are there so after getting midsurface project these engineering features onto midsurface .
go to - geometry -surface edit- extend , then edge turn into yellow color it means that edge is shares with three surfaces.
After generating midsurface without any surface connectivity errors ,do meshing each component seperalately .
go to - 2D - Automesh - element type (mixed)- element size (4)- click on mesh.

After meshing go for quality check
To give quality criteria , go to- preferences - criteria file settings
After giving quality criteria go for quality check, 2D- quality index
some elements will faile for quality try to clear thease fails using cleanup tools, node edit, edit element options.
In the above pic it shows no element will fail for quality
In the above pic one surface is over another,so connect two surface using spot weld connectors
go to-2D - connectors- spot
After clearing quality check , assign thickness to the mesh
press F4 , to measure thickness of components using two nodes option
this side door component has different different thicknesses , so put one thickness elements in one component, another thickness elements in another compnent
To create new component , right click-create -component.
while selecting elements use by face and by geometry options for selecting elements.
Create new proprty with different thicknesses
To create new property ,right click-create - property.
after creating properties assign these properties to the respective components.
To assign property, right click on component -assign-select property.

RESULT :-

BY THICKNESS MODE

2D detailed element representation mode
