Hi again,
the code is ready to unify the terms corresponding to the same integral
(weak) forms. The unified term names are obvious to choose except one:
how to call the unification of d_div, dw_div, d_grad, dw_grad? they are
all defined as $\int_{\Omega} q\ \nabla \cdot \ul{v}$ but differ in
type of variables (virtual vs. unknown). I propose dw_stokes, what do
you think?
r.
