Week 6-Meshing of Hood Challenge

AIM :

To extract the mid surface for the component and mesh the given hood component with the given target element size of 5 mm mentioned quality criteria.

Follow the below-mentioned quality criteria, mesh the component given below and assign thickness:

Target Element Length = 5mm

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

PROCEDURE :

• Import the geometry by clicking on the import option and select import geometry.
• Select the file type to '.hm'.
• Browse and select the file to be imported
• Click the import button

• Once import the cad model and and check for geomentrical issues
• In my model are facing geomentrical issues in triple cons only

• After clear the geomentical issues now go to extract the method
• 4 extract options are avalable in hypermesh in my option is (geomentry - midsuraface - offset)

• Once generated the midsurface create the component of the midsurface
• Create the material and assign the material type of the part
• Create the properties of the midsurface and assign the material and thichness
• Create the component of the midsurface and assign the properties

• After check the surfaces and feature line
• In my model unchecked surface and surface is not attached to the other surface tis issues are presented in my midsurface
• Unchecked surface area are create the new surface by using (geomentry - fillet surf )

• After finsh the midsurface geomentrical cleanup next go the mesh part
• My model is symmentric part then i will delete the one half of the midsurface

• Now are the arrage the feature line depent upon our mesh flow
• Some feature lines near to each other one of the lines are toggle
• other unwanted feature line are toggle some feature are create depent upon our mesh flow

• And now cretae the washer split aruong the hole area
• Washer splits help us better mesh flow around the area

• Now create the mesh in my midsuface
• Mainly iam focused on no opposite trais, trai are not touching each other, no bach to back trias, tias are not touching feature line and free edges
• Iam using tool for better mesh flow rebulit option, rebuilt is used for reconstruction the elements for better mesh flow
• Moving the trias front and backward is collapse option, tiras are moving sidewards is using split option
• After finsh the mesh in one half the elements are refelect to the other half by using (tool - reflect)

• And now ckeck the freee edges of the element and stritch the two half of elements
• Finally chech the assing the thickness of the properties

CONCLUSION:

In this challenge, we learn how to do a better mesh flow on the curvy region and how to handlr trains and better mesh flow.
