FESurface
The "FESurface" Object is a component of the finite element model that represents foundations or slabs. It requires at least three different "Node" Objects and a Material object, and the thickness must also be specified using the Thickness parameter.

In the above example, 8 "FENode", 4 "FELine", material class and finally "FESurface" were defined.
