Meshing and mid-surface extraction

Objective :

To import the given models and clean up their geometry before extracting mid-surface , then meshing them according to given parameters using automesh option and finally assigning them thickness using property

Procedure :

1. Open the given models and select RADIOSS interface
2. Analyse the model on its surface and check whether the surfaces are proper without free edges
   
   
   
   
3. If there are free edges , these are represented by Red color and they must be cleaned up using tools provided in hyperworks
   
   
4. Using quick edit option in the Tools menu and surface edit in geometry , the surfaces could be cleaned
   
   
   
   
   
   
5. Similarly use surface edit option to edit the surfaces
   
   
   
   
6. Use toggle option , replace point option in quick edit and Surface trim option to edit and clean the surface in surface edit
   
   
7. Delete the trimmed and unwanted surface using delete option and select surface
8. Once again check for the red lines for free edges to confirm surface clean up
   
   
9. After which extract mid-surface using mid-surface option , choose extraction method and select the surface to be extracted
   
   
   
   
   
   
10. Similarly extract the mid-surface in all the models
    
    
11. Check for any surface clean up as done earlier and edit them using surface edit and quick edit options to clean the mid-surface
    
12. Also , measure the hole's radius using distance option and select 3 nodes option to calculate
    
    
    
    
13. Remove the holes less than 5mm diameter as per requirement using quick edit options such as filler surfs for holes less than 5mm
    
    
    
    
14. Check the mid-surface completely for errors like free edges and missed out edges before proceeding to meshing
    
    
    
    
15. Mesh the mid-surface using automesh option and mention element size as per requirement
    
    
    
    
16. After meshing , check for the element's quality as per quality criteria given using check elements option in Tools
    
    
    
17. Mention the required minimum and maximum length as per requirement and check for failing elements
    
    
18. If there are failing elements , use quality index option in the 2D menu and edit the elements
    
    
19. Finally follow the same for all the given models and mesh them
    
    
20. After meshing assign thickness using right clicking --> Property in browser tab and assign thickness value in property card
    
    
    
    
    
    
    
    
21. To view the thickness , select the 2D detailed element representation in the toolbar
    
    

Result and conclusion :

All the models given are cleanedup over their surfaces , extracted mid-surface to mesh them using automesh option under defined quality criteria , and assigned thickness using property
