Week 6-Meshing of Hood Challenge

AIM: To extract Mid surface and Mesh the given model

PROCEDURE:

 Step 1:-

• Imoprt the model and check for number of components present
• Set current component as the component which you are working on
• Hide all the model and start extracting the mid surface one by one
• Firstly auto cleanup the model, so that geometry error are maximum fixed
• Suppress the edges manually which might not satisfy the quality criteria
  
• Set the quality criteria by edit criteria in autocleanup option
  
• Extract Mid surface as shown in below image
  

 Step 2:-

• Each Extracted mid surface should have new model ID
  create by right click>Create>Component
  
• Create new property ID for mid surface and assign material  to the same
• Material ID also to be created(Consider all the components are made of same material)
• In property ID the card image should be PSHELL for mid surafce and thickness of the component should be specified
• Create Property ID and Model ID for all the components

 Step 3:-

•  Automesh the component portion by portion by giving the element size as 5mm
• Make sure the mesh flow is proper and avoid opposite trias by remeshing
  
• Correct the mesh flow and check for the quality errors in 2D>quality index and
  Tools>check elements
• Fix the quality error by Cleanup tolls like Drag tria element,Element optimize, node optimize,Smooth and etc
• Below image shows the zero quality error in Inner Extract component
  

 Step 4:-

• Repeat the same procedure for all the components
• Make the sure the current part is set according to the part which you are working on
• Below the image shows there is zero quality error in the model
  
  
  

CONCLUSION:

• Understood how to clear the quality error
• Understood the concept of equivalance
• Manual geometry clean up is done
