Hello,<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

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).<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

Thank you<\/p>\n

<\/p>\n
