Hi Connor,

Connecting sheet bodies to solid bodies requires some care due to the fact that nodes on solid elements don't support rotations. It would be better to generate three sheets, assign a large thickness to the flanges and assign a small thickness to the web. If those three sheets are in a multibody part, then Shared Topology will connect them with shared nodes at the common edge. In bending and twisting, these three sheets will respond very similarly to the solid body version.
