I get the same thing when I output to VTK. In another code I am working with, I wrote a VTK outputter that would upsample higher order elements so that they actually looked higher order in Paraview. Is there anything like this (or better) in FEniCS?

WebTo implement the new term in FEniCS is straightforward. First we have to define an Expressionfor g, just as we did for f. For example, if g(x,y)=x2y, we would use In []: g=Expression('pow(x[0], 2)*x[1]') Next we add the extra term to the definition of F, which becomes In []: F=f*v*dx+g*v*ds The remainder of the program need not be changed.
