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

Aim:-  Follow the Quality Criteria and mesh the following component and assign thickness:

Target Element Length = 4 Units

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	6 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  :- 

Step 1 :-Import the model.

Import solver desk - import geometry - Iges file - import.

Step 2 :- Giving quality criteria .

Preference - criteria file settings - give the quality parameter given - apply - ok.

Step 3 :- geometrical clean up .

Replacing points :

Geometry - quick edit - replace points - select the point -= retain.

removing free edges :

Removing unwanted nodes .

Geometry - quick edit - remove points - left click to remove nodes.

Step 4 :- Defeaturing the surfaces.

Geometry - defeature - surface fillets - select the surfaces - minimum radius = 0.01 - maximum radius =4 - find -remove.

Step 5 :- Offset the surfaces or Manual mid surface.

Geometry - surface edit - offset - selelct the surface - give offset valus as mid  - duplicate the surface as current component - offset,

checking for color normal.

Step 6 :- creating manual mid surfacing .

geometry -  surface edit - offset- select the surface - duplicate to current component - give offeset value - offst.

Step 6 :- measuring distance :

geometery - distance - select one pont -select another point.

Step 7 :- Transilation.

Tool - translate - select the node - give the direction - magnitude - transilate .

step 8 :- Creating nodes and lines .

geometry - nodes - on geometry - select ponts - create nodes

Geometry - lines - linear nodes - select 1st node and select second node to create lines.

Step 9 :- Trimimg .

geometry - surface edit - trim with lines - select the surface - selelct the free lines -give direction - trim.

Step 10 :- extending the surfaces.

geometry - surface edit - extend - select the surface to extend - selelc the surface to the target - extend.

Step 11 :- Creating mid lines.

Geometry - lines - mid lines - select two lines to get a mid lines.

Step 12 :- Creating surfaces.

Geometry - surface - ruled - select the first lines -select the second line to make a surface.

after completing the geometrical clean up.

Step 13 :- Generating mesh.

2D -auto mesh  - select the surface - element size 4 - element type mixed - mesh.

mid surface has minumum element failure hence transilating the nodes.

After clearing all quality criteria.

Passes all quality criteria.

Step 14 :- Giving preview equvalance.

tool - edges - elements - display - preview equvalance - equvalace.

Step 15 :- Creating a property and giving thickness.

Step 16 :- Assigning property to the components .

Step 17 :- 2D Detail element  representation.

Final Model :-

Result :- Given component is meshed  with quality criteria and assigned property and thicknesss to the compound.

Learning outcomes :-

• Learned about mid surface of plastic component .
• learned ab out the errors and tools used.
• learned about assigning property and thickness to the plastic component
