Dear Getfem users,
I have a 3D mesh in which physical lines are identified (ie set of edges). These lines may be on the boundary or in the interior of the domain.
I would like to build a model incorporating (linear and even nonlinear) terms on these lines (ie integration domain of dimension m.dim()-2). This could be used for example to model a concentrated line of current injection in an electric ohmic problem (rhs term) or a lineic domain of high conductivity (contributing then to the matrix term). Is there any way to do so in Getfem?
Thank you in advance
Best regards
Jean-François Barthélémy
