Thanks Paul, so it is already implemented. It sounds awesome. Thanks again, Best Simone On Oct 7, 2016, at 13:34, Paul T.

[Libmesh-users] Surface PDEs
Dear all, I’d like to extend my libmesh-based reaction-diffusion solver to a surface solver, taking the trace of the 3D shape functions on the surface mesh. Before I start implementing a new element, do you have any suggestion on how to approach it?
