Alberto, be aware of the fact that, when you extract the boundary mesh, the orientation of the cells may be different w.r.t. to the corresponding face on the volumetric mesh. In other words, using FEValues codim_one(…); FEFaceValuescodim_zero(…); codim_one.reinit(codim_one_cell);

Dear community I am trying to find a good way to deal with the following problem. I am interested in a Laplace-Beltrami simulation (say with unknown scalar field c) on a surface that advects (with displacement field u) enclosesing a volume of say elastic material. The two problems are per se
