Week 6- Challenge

Objective: Meshing of Hood according to given quality criteria using Hypermesh .

Given quality criteria

Target Element Length = 5mm

Procedure :

Import the given cad model into hypermesh
threre are 5 components in model , so do meshing individually
First i taken LATCH component
before go for meshing , we have to do geometrical clean up
meshing on 3D component is difficult and time taking process ,so we extract the mid surface of latch component
create a new component and name it as latch mid surface and move the middle surface into this component
after getting mid surface , we should remove toggle edges , unwanted holes , fillets etc..
so for geomery clean up , we can use auto cleanup
and i gave washer split of 5mm
after getting mid surface and geometrical clean up , we should do meshing
for 2d mesh , go to auto mesh command and give element size is 5 and select element shape as quard
after meshing work on mesh to get proper mesh flow and to acheive quality criteria given
use QUALITY INDEX , EDIT ELEMENT , SMOOTH ,CHECK ELEMENTS , ALLIGN commands

HING BODY2 :

INNER EXRACT BODY:

this is a complicated component so while extracting mid surface there is a chance for error in mid surface , so change the mid surface option to OFFSET+ PLANE
after getting mid surface do auto clean up and follow same procedure mentioned above
while meshing some gaps comes in mesh so fill the gaps by using edit element option
