How to connect two different existing meshes with CBUSH elements?

Hi guys, I have two panels with different meshes connected by CBUSH elements. I have now received new vectors/locations for CBUSHs. What is the best method to add these new CBUSHs if I don't want to re-mesh anything because I need to keep the previous QUAD element IDs? CBUSHs should connect coincide nodes. Maybe some new tool exists that will move the nodes automatically while preserving elements? Thank you!

    hello @Vladimir_Gantovnik ,

    if you don't wan all all your 2D mesh to be altered, I would recommend to import your new CBUSHs in your existing model, then to use equivalence to associate shell nodes with the cbush elements.

    Obviously, this will work properly only if the CBUSH nodes are closed to the shell nodes.

    Otherwise I would add a second step to apply some local smooth on the 2D elements with a bad quality

    Regards,
