Hello Wolfgang,
thank you for the hint.
This is just what I was looking for. I think I can simply copy the
VectorTools::no_normal_flux_constraints, because this function actually
only deals with the difficulties on finding the correct normal vectors.
What I have to do is to implement an equivalent to the
internals::VectorTools::add_constraints function, where the creation
and addition of the constraints takes place, but this looks straight
forward.
Best Regards,
Markus

Did anyone already implement something like this or does anyone know how
to do it?
I don't know of anyone who would already have done that. But you may want
to look at the VectorTools::compute_no_normal_flux_constraints function,
which has quite some documentation on how to compute the constraints for
the boundary condition
n cdot E = 0
I would imagine that you can compute constraints for the tangential
conditions in a similar way.
Let us know if you need help!
Best
W.
