| Popis: | Decomposing conductor models from the entire physical domain, a coupled simulation approach has been a common idea to associate the large-scale magnet simulators. To date, simple feedforward reciprocating is taken for granted to assign the interface values of each individual solver at every time step. In this paper, a breakthrough is made to improve the numerical stability of a coupled thermohydraulic model out of the limit of the generic way. Exploiting the established code package of CryoSoft, the novel coupling scheme is implemented to the existing thermohyraulic solver for CICCs to cooperate with their forced flow circuit. As a result, its improved stability is proven with the SuperMagnet based integration of the conductor models, i.e., the THEA models in the KSTAR magnet simulator. Then, an alternative approach is examplified using an FMI-wrapped THEA model, to be connected to the hydraulic components in the OpenModelica environment, in the same context of the proposed coupling scheme. |
