Hello,everyone.  
As for FreeFEM, I know that the interpolation mode of its elements is all in the form of triangles. We can also improve the accuracy by adding nodes on the edges of triangular elements. My question is, what should I do if I want to use bending plate elements based on thin plate theory (such as Kirchhoff plates)?
