Meshing with mid-surface extraction and assigning thickness

Objective :

To mesh the given component by extracting mid-surface manually and also assign thickness accordingly

Procedure :

1. Import the the and choose RADIOSS interface
   
   
2. Analyse the component and look out for any geometrical errors on its surface and edit them using Quick edit option
3. Split the component into 4 for the convenience
   
   
4. Use trim with surfs/plane option and select axis and base point
   
   
   
   
   
5. For better identification , select the surfaces and differentiate them by different colours and move them to different collectors
   
   
   
   
6. Edit the surface before creating mid-surface by using quick-edit , surface edit options
   
   
   
   
7. Remove fillets whose sizes are less than the target element size for meshing using - Defeature option and choose surface fillet
   
   
   
   
8. To extract mid-surface manually , first calculate the distance between the surfaces using distance option and calculate the half the distance
   
   
   
   
9. Create mid-surface by using offset option in surface edit
   
   
10. Select the surface and mention the distance
    
    
11. Before offset , Duplicate the surface and using reverse normal if required
    
    
    
    
12. Similarly calculate distance for each surfaces and make individual collectors
    
    
13. Create individual mid-surface for each surface calculated accordingly and move them to respective collectors
    
    
    
    
14. Edit the surfaces and prepare for meshing
    
    
15. Select the individual mid-surfaces created that are moved to respective collectors , mesh them individually using automesh option
    
    
    
    
    
    
16. Follow these for all the surfaces and create individual mid-surface, meshing and move to individual collectors
    
    
17. Create property in the tool tab area by right click --> property
    
    
18. According to varioius thickness size , create various property and enter thickness range
    
    
    
    
19. Now select the collectors individually and then assign thickness to them accordingly
    
    
    
    
20. Thickness assigned to the mesh can be viewed using 2D detailed element representation
    
    

Result and Conclusion :

For the given plastic component , mid-surface has been extracted according to thier difference in thicknesses and also meshed them and then assigned thickness using property
