Hi Lorenzo,
we consider equations of the form
ds/dt - div(f) = q
by setting Neumann BC it is always meant that f*n is specified on the
boundary, where n is the normal vector on the boundary. Now the boundary
flux f*n can be a constant but it is also allowed to depend on any
variables
Good afternoon,
after having searched on internet, I didn't find the info which I need.
Could you please explain the details of the implementation of the
Outflow (even if it has been removed in the new release) and Neuman BC
in DuMux and in what they differ, please? In particular, in the
