Dear all, Is there a way with the getfem python interface to assembly the matrix associated to the interpolation matrix of a first derivative evaluation of a fem (or its full gradient). I found
Mi = asm_interpolation_matrix(MeshFem mf, vec pts) for the evaluation of the function u = MeshFem mf itself, but I was not able to identify the relevant generalization for derivatives of u: \partial u_x, \partial u_y, etc. Thanks a lot for this great library, best, Edouard. -- Edouard Oudet : http://www-ljk.imag.fr/membres/Edouard.Oudet/ IMAG - Bureau 164 700 avenue Centrale 38400 Saint Martin d'Hères +33 (0)4 57 42 17 71 (office LJK) +33 (0)4 79 68 82 06 (home)
