A combined domain decomposition - model order reduction technique for fast finite element parametric sweeps

We have presented a combined DD-MOR method, which extends existing approaches by incorporating the DD in the generation process of the ROM. The DD method allows the efficient use of a multipoint MOR procedure, since only the subdomain containing parameter-dependent features has to be solved at the ROM interpolation points. In future work, we will extend our approach to frequency and geometry parameters, and demonstrate its efficiency in optimization scenarios.
