Splitting a surface does not automatically fix the mesh

Hello Everyone,

 

i am having a problem with Hyperworks version 2017.2. I have an already meshed model.When i delete a mesh on one surface and then mesh that surface again,  the new elements don't attach to the ones on the adjasent surface, although both surfaces are attached to each other. Does anyone know how to solve this probelm, without having to remesh the model? Also when remeshing a surface without deleting the mesh on it before, the new mesh just sits above the old one as if it were not there... So i get 2 meshes above each other. Can someone please help?

 

Thank you!

    Hello,

     

    Please make sure that the first time you meshed the 'keep connectivity' option was ticked in the automesh panel.

    Also,

    When you remesh a surface from the drop down select elements instead of surface.

    Thank you!

    Now the mesh is not doubled, perfect.

    But the thing is, it is i didn't mesh the model the first time so i don't know what the setting was. So i still don't have the connectivity between the two surfaces.. Is there any other solution?

    Even when i mesh the blue and the green surfaces, after deleting the elemtns on them, i don't get a connectivity between both surfaces.. What could be the problem? It's like i'm meshing two different surfaces that are not attached at all... Although the line splitting both surfaces is green!

    From the above pictures i can see that the mesh is connected.

     

    Can you please post some more pictures of the new mesh.

     

    Thankyou
