Week 12:Project 2-Meshing of Rear Wheel Holder challenge

AIM :- Mesh the given floor pannel component with below mentioned quality criteria and assign thickness.

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	8 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

Procedure :- 

• Import  the given .hm file into hypermesh , go to - import model- select file - click on import .
• 
• Given model splitted into 21 components, delete the unwanted components and organize all required components in single collector.
• 
• To move components from one collector to another collector , go to- tools- organize-select surfaces- click on move.
• Now it is a single component , it is difficult to create midsurface for these kind of single complicated components.
• Split the component into 4 pats, go to - geometry - surface edit - trim with surf/plane- select surface and direction [axis]-click on trim. 
• 
• After this do geometry cleanup for each component.
• 
• Radius of this geometry is 2 ,it is difficult to capture these features with required quality so consider these features as pin holes and remve it.
• To measure , press F4 ,choose 3 points option.
• To remove pin holes , go to geometry - defeature- pin holes 
• 
• Do the geometry cleanup for all components , using quick edit, surface edit options mainly.
• After completion of geometry cleanup create middle surface for components .
• go to - geometry -surface edit - offset - select surfaces - give offset distance- click on offset.
• 
• check for connectivity errors, it means is there any free edges or any missed or duplicate surfaces like that.
• 
• Above pic shows the total midsurface of floor pannel component in topo view mode without connectivity errors.
• Mesh the each component seperately , go to- 2D-automesh - select surface - element type [fixed] - size [5]- click on mesh.
• After meshing go for quality check .
• To give quality criteria , go to - preferences - criteria file settings .
• 
• to check, go to- 2D - quality index 
• clear the all failed elements  using cleanup tools[quality index], edit element [2D] ,smooth and node edit options.
• 
• After clearing quality check foe edges , go to -tools - edges- elements - select all - preview equivalence - click on eqivalence.
• 
• Still some elements have edges, to clear this use replace[2D] option 
• 
• 
• above pic shows there is no free edge between elements and all elements have proper connectivity.
• It is a uniform thickness  component, so single property is enough
• To create property  , right click- create- property .
• 
• assign this property to the components 
•  
• to view thickness change view mode to by property and put in 2D detail element represention.
• 
• mask some elements  and see whether thickness is applied or not.

RESULT  

Meshed the floor pannel component with given quality criteria and assigned thickness.
