Domain decomposition methods (DDM) are often chosen to precondition sparse linear systems of equations, as they are famous to well-improve the convergence of iterative solvers. But at the same time, they are difficult to implement and can be computationally expensive. In this work a new mesh numbering to adapt preconditioning techniques to the physics of different problems is proposed as an alternative to DDM preoconditioning.
