WebbThe property that each of the basis functions is 1 at its associated vertex, and 0 at the other three vertices means that the set of basis functions is a Lagrange interpolation basis for the vertices. Using our basis function notation, the solution to the interpolation problem has the very nice form: f(x;y;z) = fa˚ a(x;y;z) + fb˚ b(x;y;z) + fc˚ WebbAdd a circular surface to the center of the square. To make a structured mesh in gmsh, shapes with four sides are needed. At this point, the circular shape can be meshed with a structured algorithm, but the region outside of the circle can't. This region is next broken into four sided shapes as shown in the input below.
