Consistent and convergent discretizations of Helfrich-type energies on general meshes

Vincent Degrooff, Peter Gladbach, Heiner Olbermann

We show that integral curvature energies on surfaces of the type $E_0(M):={\int }_{M}f(x,n_M(x),D{n}_M(x))d{\mathcal{H}}^2(x)$ have discrete versions for triangular complexes, where t…
