Abstract:
A time-discontinuous space?time formulation for the ??divide-and-conquer?? multiscale method is presented. This multiscale method aims at stable and accurate solutions of transient convection?diffusion-reaction problems. The method is constituted by a time-discon- tinuous space?time finite element method on the fine-scale level, an explicit procedure for advancing the coarse-scale solution on the respective level, and inter-scale operators providing the data transfer between the coarse- and fine...     »
