I want to decompose a 3D mesh (sphere) into multiple subdomains and export the stiffness matrices / load vectors to solve the problem with an external CG solver. Unfortunately it seems that the local matrices are non-symmetric. // ff-mpirun -np 4 sphere2.edp -wg -ffddm_overlap 2 -ffddm_schwarz_met…

Thank you very much, that was really helpful.

Can I export the restriction matrices and the decomposition of the one as well?
