In this talk we review the classical non-overlapping domain decomposition (NODD) preconditioners, together with the newly developed multi-scale control volume (MSCV) method. By comparing the formulations, we observe that the MSCV method is a limited special case of a NODD preconditioner. We go on to suggest how the more general framework of NODD can be applied in the multi-scale context to obtain improved multi-scale estimates.
These results are placed in the setting of a more general comment on the development of multi-scale method.
