NOTES

1. This section defines a distribution of thickness a surface. This thickness distribution is used for shell or membrane elements. Thicknesses will be defined at the nodes of a rectangular grid over the surface that defines the geometry of the shell or membrane. The u and v coordinates of this NURBS surface will be used to defined the grid points. At first, the number of grid points nu and nv along the u and v coordinates, respectively, are defined. Next, the nv grid points, v₁, ..., v_nv, along the v axis are defined. Note that v₁ = 0.0, v_nv = 1.0, and the intermediate values must appear in ascending order.
2. The actual thickness table consists of the definition of the thicknesses along nu columns parallel to the v axis. Each column starts with the u_i entry at which is is located, followed by the nv thicknesses at the nv grid points of this column. Note that u₁ = 0.0, u_nu = 1.0, and the intermediate values must appear in ascending order. At any point on the surface, the thickness is linearly interpolated among the four closest grid points.
3. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
