[Libmesh-users] Shape functions at boundaries

Hello, I am trying to implement a formulation for contact mechanics using the FEMSystem. This involves some contributions at the surface being in contact. I add these contributions in FEMSystem::side_time_derivative(bool, DiffContext& c). For this contribution I need the derivatives of the shape-f
