Hello :) When I copy&paste DualFormulations example from wiki[1] (http://geuz.org/getdp/wiki/DualFormulations) run gmsh dual.geo, build 2D isotropic mesh, run getdp with dual.pro (from gmsh menu) on saved dual.msh, than I end up with GetDP: Error : Zero row encountered in ILU Can anyone please confirm this? Thank you in advance... [1] login: getdp passwd: wiki Best regards Michal
