Dear Andriy, There is FEM_HERMITE(3) but of course, it is not a fully C^1 element (but it can give good results). In 2D there is also the Argyris triangle (degree 5) but I don't know if there is a simple generalisation in 3D (in fact Argyris triangle element is himself not very simple). I don't know neither is there is simple generalisation to the 3D of piecewise third degree polynomial HCT and FVS elements . In fact, these elements are mainly used in thin structure model that are one or two-dimensional problems only.
So , you have to have a good reason for using C1 conforming element in 3D ! May be you can avoid them. Yves.
