Interface element

Hi Everybody
I need a help
In my model I have steel beam attached to concrete slab and I wnat to privide interface element between them, all are brick elements HX24L. Is it necessary to have a gab between them to be filled by the interface element or the I can apply this interface element on the surface between them.
Thanks

Are you using idiana or FX+?
In idiana you need to create a body for the interface element. This body may have a zero height. It is good practice to create a body with a non-zero height, check the meshing and then move the top and bottom surface towards each other to create the zero height.
I don't know the correct procedure for FX+

Hi MZAYED,
If you are working in FX+ you can use:  MESH --> ELEMENT --> CREATE INTERFACE ELEMENT. There no need to have a gap. Please see the "DIANA frequently asked question --> Midas FX+" in Support of tnodiana.com.
Bye
