Mesh generation with Gid

The mesh generation in Gid is very similar to tutorial 1, so it is not repeated here. We just remark that the element size, as required in the Gid Mesh - Generate dialog should be set to $1.0$ to get a reasonably fine mesh.

Figure 8 shows the Nurbs surface. Figure 9 shows the mesh.
