Computation of complex structures using the State Space Concatenation Scheme — •Johann Heller, Thomas Flisgen, and Ursula van Rienen — Institut für Allgemeine Elektrotechnik, Rostock, Germany

For the design and operation of radio frequency (RF) structures for high energy physics, the knowledge of the electromagnetic fields inside such structures is of crucial importance. These fields are computed numerically by solving the curl-curl equation, derived from Maxwells equations. For large and complex structures, due to the huge size of the problem the field patterns can not be computed on standard workstation computers in reasonable time. Actually, for such type of problems, sophisticated parallel codes are employed on high performance computers (HPC). Being very expensive, HPC platforms are rather rare and have a very limited access. Therefore, we recently proposed a concatenation scheme, denoted as State Space Concatenations (SSC), which is able to compute complex RF structures on standard workstations. In this contribution, we will present very promising results of performance studies related to FLASH and the European XFEL.
