These systems are subsequently used for testing iterative solvers and preconditioners. The code is characterized by: simplicity and possibility of easy modifications, directly solving model problems on square domains (generalization possible), controlled random coefficient oscillations (stochastic generation of heterogeneity), fast system assembling using vectorization and sparse reconstruction, possible testing of Krylov type solvers with both (block) matrix and matrix free (variable) preconditioners.
