Issues with shell elements seperating
I am having some issues with surfaces separating in simulation (explicit dynamics). I have a tubular chassis with two different thickness (2mm & 2.5mm. Both geometries are grouped within their respected folders and then in one top level folder containing both.
I have shared the topology on the top level but the surfaces still separate in the simulation (before any contact has even been made also).
You have told me on here previously that If "shared topology" has been applied then there is no need to define connections within the solver. However I get the same issue regardless whether I include it or not.
Is this possibly an issue with my shell element creation process? I have tried to best capture some images below to help give you an understanding into my problem.
