Week 6-Meshing of Hood Challenge

Objective : Clean up geometry.create midsurface and meshing on its as per quality criteria .

• methodology :

1. import a model
2. create midsurfac
3. clean up geometry
4. meshing as per quality criteria
5. automesh
6. check the qulity

- free edges

- qulityindex

- check elems

- element to surface check by the comparision

- geaometry check

- normal check

- dependency

-

model name : hood.stp

Procedure:

• The format of the file is stp , then first of all select import solver deck command , choose import geometry type and select file type is STEP

  -now select the file from our folder and import it .

  -but it is not visible on our screen due to graphical issue , for that use f key and then its visible
• 
• after import model delete the solids part of the hood model.
• split part of the hood model
• work on model and process to automesh after check the qulity .
• 
• frist part of the model is latch
• and frist process step is geom -> auto midsurface -> extract -> reture.
• 
• 2nd step is the remove the unwanted node because of effect on the meshing elems and other step is use the toggle edge the commands
• autocleanup is not good wrok on compilcated model.
• 
• apply the automesh and work on it .
• them check the qulityindex
• 
• after we are go for the next "check elems" where check the the warpage , aspect ratio , skewness ,lenth mim and max , jacobian , mim and max angle for trias ,mim and max angle for quads them return.
• 
• here is given some criteia which we are follow the parameter for qulity check.
• 
• step is geom -> auto midsurface -> extract -> reture.
• 
• check the penetration them here we see the thickness the is missing " unexpecited thickness" .
• 
• after add the material them add the property and given the thickness
• 
• after the apply the thickness and cross check error them we see error is clear.
• the part the comp. compeleted
• 2nd part of comp is hinge
• 
• frist process step is geom -> auto midsurface -> extract -> reture.
• 
• 
• after the meshing we go the qulityindex. as if where show the worse mesh elems them correct wiht the some give command .
• such command just like place node , smooth, drag element , combine and optimize element .
• 
• after we are go for the next "check elems" where check the the warpage , aspect ratio , skewness ,lenth mim and max , jacobian , mim and max angle for trias ,mim and max angle for quads them return.
• 
• after that check the mesh follow the some step mesh -> check -> element -> comparion
• then apply the surface and elems after that run and apply.
• 
• them apply the normal for the froce apply.
• 3rd part of comp is outer part.
• 
• step is geom -> auto midsurface -> extract -> reture.
• 
• 
• 
• after that check the mesh follow the some step mesh -> check -> element -> comparion
• then apply the surface and elems after that run and apply
• 
• 4th part of comp is inner part.
• 
• frist process step is geom -> auto midsurface -> extract -> reture.
• \
• 
• after the meshing we go the qulityindex. as if where show the worse mesh elems them correct wiht the some give command .
• such command just like place node , smooth, drag element , combine and optimize element .
• 
• 
• when i am check the mim and max angle the element break the angle limit.
• 
• them correct the angle the using reverse mask
• 
• them check the normal .
• 
• final model of hood
• 

Result: The given hood assembly is successfully meshed according to the provided and quality checked.

Conclusion: In this challenge, we learn how to mesh the hood component
