Week 7- Meshing of Backdoor Challenge

OBJECTIVES:-

• mesh the backdoor geometry of a car with quality parameter given

PROCEDURE:-

• open the hypermesh
• import the geometry by using import geometry option and select type of file then select the file ,click import
• here 2 part are given with symmetry centre axis
• delete one of the half of the geometry and move the each geometry to seperte collector by using organise in tool panel
• check for geometry error and fix it with appropriate methode
• 
• extract mid surface for each geometry
• 
• do a geometry clean up based on element size (toggle line which cause fail to keep minimum element size )
• input quality criteria as given
• input mesh size as 5
• mesh difficult or complex are firstly by using automesh in 2D panel
• rearrange mesh flow using rebuild mesh or automesh in 2D panel
• avoid triangle from free edges by using swap and spit option given quality index
• if fillet size are very small to keep minimum element size keep centre line and toggle other line
• increase mesh flow using smooth option in 2D panel
• add property and material then assign to collector
• 
• 
• 
• check for edges using edges option in tool panel
• fix the unwanted edges using equivalence option in edges
• if there any free edges still shown then fix it using replace ,paste nodes of the element
• 
• finish the callenge
