Shell to Shell Connection

SarveshSarvesh
Hello Victor,
I would greatly appreciate your guidance on handling shell elements in Mecway. I may lack sufficient expertise in working with shell models. I have imported a pre-meshed shell model consisting of three plates but struggle to stitch or bind them together for further analysis. How can I manage independent shell element connections with varying thicknesses within Mecway?

    You can use Contact with Bonded option, but you need to remove the first two faces of the slave surfaces (because they are also restrained by the Fixed boundary condition).

    You can fuse the faces in CAD and export as one step file, and then mesh with coincident nodes to replace the Contact/Bonded boundary condition.

    If you want to use the CCX solver, choose TIE as the option in the Contact bc and use an adecuated position tolerance

    By the way, you have meshed the part with coincident nodes! You only need to stich all of them with an adecuated position tolerance such as 1mm and don´t need to use any contact bc! See the last picture
