Hello,
Let V = HDiv(mesh, order = order, dirichlet="bottom|right|top|left")
Is it possible to compute the jump of a function u \in V in the tangential direction? I tried a few things, among others, using u.Other(), but this gives me the following error
illegal dnumsin Assemble BilinearForm 'bfa'.
I'm trying to implement the weak form (4.20) of the following paper:

Thanks,
