Hi Georg,
I guess that you mean Robin boundary condition, namely, prescribing
a.u + b.du/dn = g
for an unknown u at the boundary?
Then you can use the "solDependentNeumann" function in your problem file
instead of "neumann" or "neumannAtPos". An example is provided in
test/implicit/1p/1pniconvectionproblem.hh. With the notation above, you
would prescribe
du/dn = 1/b . (g - a.u)
Kind regards
Bernd

Hello DuMuX users,
Is there a possibility to set a Cauchy boundary condition in DuMuX. If
so, how does it work?
Best regards
Georg Futter
