Week_8_Plastic Model_1

Aim:-Create a midsurface and mesh of plastice model according to given quality criteria. That mantion below

Element quality criteria :

S.N	Quality Criteria	Value
1	Target Element Length	5 mm
2	Aspect Ratio	3
3	Skewness	45
4	Warping	30
5	Taper	0.5
6	Min. Length	3 mm
7	Max. Length	7 mm
8	Min angle Quad	45
9	Max angle Quad	135
10	Min angle Tria	30
11	Max angle Tria	110
12	Tria %	15

Object:- Create a midsurface and mesh

loade model:-

When i uploade model in hypermesh and go by topo, then i saw it is a solid , so that i am go delete option and select solid and delete it.

Before deleting	After deleting

2.Geometery cleanup:-

After achiving surface, when chack geometery it already cleane so that i did not need to cleane the geometery.

3. Midsurface:-

• After geometery cleanup , we ready to taking a midsurface
• Geo>midsurface>offset+plane+swe.
• And take midsurface via these command that mantion above.

4.Meshing:-

• Before taking a mesh ,we setup quality criteria, and than create a mesh.
• 2D>Automesh>select surface and do mesh.

5.Fix falling element:-

• After meshing ,we chack quality of mesh for this we go 2D>qualityindex>cleaning tool.
• And using some tool like split/collapes edges,swap edges,drage tria,element optimize etc.

Conclusion:-

1. I trey to better mesh and meshing.
2. this model have some difficult part that difficult to taking midsurface.
