Auto repair function

Hello colleagues,

I am trying to mesh a helmet on HyperMesh and I am not able to select the liner as a solid (just components and surfaces are enabled to selection). Does anybody know if the command "auto repair" or a similar one is present in version 2019.1 and if it is the way to solve this issue?

Best regards,

    @Ricardo Azevedo You can stitch the surfaces to a solid if you dont have cracks larger than tolerance. The below option should help you get to a solid. (Ctrl+F in HyperMesh)

    Not clear within which tool you are when you mention - "just components and surfaces are enabled to selection"

    Hello Ricardo, 

    As you cannot select a solid in the tetra mesh function, it means that your geometry is only surfaces.

    These surfaces could be openned.

    You can change the visualisation option to check that. 

    By default you are in automatic visaulisation, if you switch to topology, you can review the the color on the edges and on the surfaces.

    To check that could you follow these steps :

    1. Try to recreate a solid -> your surfaces could be well connected and only the solid entity is not created.
      1. Go to the geometry ribbon
      2. Solids icon and select Bouding
      3. Pick one surface on your helmet, if all the surfaces are selected it means that the surfaces are well connected and you can create your solid
      4. If the surfaces are not selected follow the step 2
    2. Repair the geometry by stiching surfaces
      1. In the geometry ribbon go to the Stich icon, use the first part of the icon named “stich surfaces”
      2. Select all your surfaces by a window
      3. Respect to a tolerance, your surfaces will be stiched.
      4. Try again the step 1 to check if you can create a solid
      5. If you cannot, it means that you have a bigger gap between your surfaces and you need maybe to recreate surfaces
    3. To identify the area where you have an issue, check the free edges (red lines)

    If you still have an issue, could you share your model and I will give you the best way to fix your model.

    Thanks,

    Richard
