The physical beam is meant for this kind of situation. However while running a simple test I ran into an issue with the meshing when the physical beam is used with the mat. So please hold off on using that option. I have requested our development desk to investigate this issue. Using the beam at the edges would change the boundary condition for the mat slab and hence I would expect the moments to reduce. For now using a control region with a higher thickness assigned to it, is an option worth trying out.
